In electronics, rectification is a process of converting alternating current into direct current. In the actual circuit, it is necessary to use a rectifier circuit to convert alternating current into direct current in order to supply power to electronic equipment. Rectifier diode ISO124P is a component used to convert alternating current into direct current. It is a semiconductor device, usually made of silicon or silicon carbide. Rectifier diode It is a bidirectional conductive device that can pass current under forward voltage and prevent current from passing under reverse voltage. Rectifier diode Properties of Rectifier diode Its characteristics mainly include forward voltage drop and reverse breakdown voltage. The forward voltage drop refers to that under the forward voltage, Rectifier diode The voltage drop generated internally is usually 0.5V~0.7V. This is because Rectifier diode When the PN junction of is biased in the forward direction, electrons and holes will combine and release energy, making Rectifier diode The internal voltage decreases. Reverse breakdown voltage means that under reverse voltage, Rectifier diode The phenomenon of breakdown will occur and a large amount of current will be generated. The reverse breakdown voltage is Rectifier diode The maximum withstand voltage is usually several hundred volts to several thousand volts. Rectifier diode Classification of Rectifier diode It can be classified according to its structure, working mode and maximum rated current. 1.

Zener diode is a common electronic component, which can stabilize the voltage within a certain range, so that the circuit can work normally. Zener diode is widely used in power supply, SN74LVC1G125DBVR amplifier, computer, communication and other fields, and is an indispensable part of modern electronic technology. This article will introduce in detail the working principle, types, parameter selection and application of zener diode. 1、 Operating principle of zener diode The zener diode is a semiconductor device with PN junction structure. Its operating principle is similar to that of ordinary diodes. Under the forward voltage, the current of the zener diode is linear with the voltage, while under the reverse voltage, the current of the zener diode changes exponentially. Therefore, the zener diode can stabilize the voltage through reverse voltage. The operating principle of zener diode can be simply divided into two stages: forward conduction and reverse cut-off. 1. In the forward conduction stage, when the forward voltage of the zener diode reaches a certain value, the carrier in the PN junction begins to diffuse to the opposite side, forming a forward current. At this stage, the current of the zener diode is linear with the voltage, and its current is limited by the external circuit. 2. In the reverse cut-off stage, when the reverse voltage of the zener diode reaches a certain value, the electrons and holes in the PN junction are separated by the reverse electric field, forming a space charge zone. At this time, the current of the zener diode drops sharply, and remains at a small value. At this stage, the current of the zener diode is almost unaffected by the external circuit, and its reverse current is determined by the characteristics of the device itself. 2、 There are three types of zener diodes: Zener diode, LED zener diode and TVS diode. 1. Zener diode Zener diode is a diode with special voltage current characteristics, which can stabilize the voltage within a certain range. The operating principle of Zener diode is similar to that of ordinary diode, but its voltage current characteristic is inverted U-shaped, that is, within a certain voltage range, its current increases very little, thus realizing voltage stabilization. 2. LED voltage regulator diode LED voltage regulator diode is a new type of voltage regulator

BAT54S is a two-way Rectifier diode , composed of three PN junctions, can be used for rectification, protection, voltage limitation and other aspects of the circuit. Its main characteristics are small size, low power loss, fast response speed, etc., so it is widely used in electronic circuits. 1、 Structure and Principle of BAT54S BAT54S consists of three PN junctions, two N-type semiconductors are anode, and the middle P-type semiconductor is cathode. When the forward bias occurs, the middle P-type semiconductor and the N-type semiconductor at both ends form a PN junction. The electrons flow from the N-type semiconductor to the P-type semiconductor, and the holes flow from the P-type semiconductor to the N-type semiconductor. The current can pass through. When reverse bias occurs, the P-type semiconductor in the middle forms a PN junction with the N-type semiconductor at both ends. The electrons flow from the P-type semiconductor to the N-type semiconductor, and the holes flow from the N-type semiconductor to the P-type semiconductor. The current cannot pass through. Therefore, BAT54S has a single conductivity and can be used for rectification, protection and other aspects. 2、 Parameters and specifications of BAT54S Maximum DC reverse voltage: 30V Maximum average rectification current: 200mA Maximum peak reverse current: 0.5A Operating temperature range: - 65 ℃~+150 ℃ Package form: SOT-23 III. Application of BAT54S BAT54S is often used in rectification, protection, voltage limitation and other aspects of electronic circuits. For example, reverse protection in the circuit: in electronic circuits, it is often necessary to reverse protect the components in the circuit to prevent the circuit from being damaged due to excessive reverse voltage. At this time, BAT54S can be used as the reverse protection diode. When the reverse voltage exceeds its maximum rating, BAT54S will limit the voltage below its maximum rating to protect the devices in the circuit. Rectification in circuit: BAT54S can be used as Rectifier diode To convert alternating current into direct current. For example, in the audio amplifier, the AC component of the input signal needs to be removed and the DC component needs to be retained. At this time, BAT54S can be used as the Rectifier diode 。 Voltage limitation in the circuit: BAT54S can be used as a voltage limiter in the circuit to limit the voltage in the circuit below its maximum rating. For example, in LED drive

This power circuit is powered by 12 V AC Rectifier diode Form VD1 In the VD4 rectifier bridge circuit, the voltage after rectification is stable - capacitors CI, C2, zener diode VD5 and transistors VT1 and VT2. The output voltage of the power supply from 0 to 12 regulates the variable resistor R2.

Variable resistor R2 - power switch, which is a desirable group A, its scale, on which the output voltage of the power supply is set is equal numbered. Can be used in MP39 MP40 transistors, rather than transistor stability MP42, not P213 - P214 P217 transistor, P201, P4 and any letter index. The gain of the transistor must be at least 15. Zener diode D813 can replace Zener diode D811, D814D D814G. The maximum pressure of the power supply output voltage will correspond to prevent Zener from stabilizing. The scale of the resistance R2 should be calibrated to the model of the voltmeter connected to the output terminal block.

1) For series power circuits Rectifier diode , should select Rectifier diode The maximum rectification, current and reverse working voltage of the diode meet the requirements. 2) For switching voltage stabilizing circuit Rectifier diode The fast recovery type with high operating frequency and short reverse recovery shall be selected Rectifier diode 。 Instead of ordinary Rectifier diode 。 FR series, PFR series and MUR series fast recovery diodes can be selected. 3) Low voltage rectifier circuit with low forward voltage drop shall be selected Rectifier diode 。 4) For rectifier circuits below 5A, ordinary Rectifier diode 。 For example, 1N4000, 1N5200 series silicon plastic packaging can be used for half bridge, full bridge rectifier circuit, power circuit of radio recorder and general low-voltage rectifier circuit Rectifier diode 。 You can also choose 2CZ series Rectifier diode 。 5) Rectifier diode Principle of substitution: ① Diode substitution with parameters basically the same as those of the original diode can be selected. ② The diode with large rectification current can replace the diode with small rectification current, otherwise, it cannot be replaced. ③ The diode with high reverse operating voltage can replace the diode with low reverse voltage, on the contrary, it is impossible to replace it. ④ The diode with high operating frequency can replace the diode with low operating frequency, but it cannot be replaced. Common Rectifier diode The main parameters are shown in Table 12 and Table 13 for reference. Table 122CZ Series Partial Diode Parameters Table 13 1N Series Partial Diode Parameters

In switching power supply Rectifier diode It must have the characteristics of forward voltage reduction and rapid recovery, and it should also have sufficient output power. The following three types of Rectifier diode : Rapid recovery Rectifier diode ； Ultra fast recovery Rectifier diode ； Schottky barrier Rectifier diode 。 Fast and ultra fast recovery Rectifier diode It has moderate and high forward voltage drop, and its range is 0.8~1.2V. These two Rectifier diode It also has high cut-off voltage parameters. Therefore, they are particularly suitable for use in low power auxiliary power supply circuits with an output voltage of about 12V. Since the operating frequency of modern switching power supply is more than 20kHz Rectifier diode , rapid recovery Rectifier diode And ultra fast recovery Rectifier diode The reverse recovery time of Sa Ⅱ is reduced to the nanosecond level, so the efficiency of the power supply is greatly improved. According to experience, when selecting rapid recovery Rectifier diode The reverse recovery time should be at least 1/3 of the rise time of the switching transistor. These two Rectifier diode It also reduces the switching voltage spike, which directly affects the output DC voltage ripple. In addition, although some are called soft recovery Rectifier diode However, their reverse recovery time is longer and the reverse current is larger, which increases the switching loss and cannot meet the working requirements of switching power supply. Rapid recovery Rectifier diode And ultra fast recovery Rectifier diode Whether heat sink is needed when switching power supply is used as rectifier device depends on the maximum power of the circuit. Generally, the allowable junction temperature of these diodes during manufacturing is 175 ℃, and the manufacturer has technical specifications for this indicator to provide designers with the ability to calculate the maximum output working current, voltage, housing temperature, etc. Schottky barrier Rectifier diode Even under the action of large forward current, its forward voltage drop is very low, only about 0.4V. Moreover, with the increase of junction temperature, its forward voltage drop is lower, so Schottky Rectifier diode It is especially suitable for low voltage output circuits of about 5V. Schottky barrier Rectifier diode The reverse recovery time of

Discuss the secondary side of Flyback Rectifier diode RCD absorption is better than RC absorption in dealing with such peak problems. With RCD absorption, the peak voltage of the rectifier tube can be lower (with reasonable parameter matching, it can be completely absorbed, and the peak voltage can hardly be seen), and the absorption loss is also smaller. Rectifier diode Voltage waveform (RC absorption) Rectifier diode Voltage waveform (RCD absorption) From the two simulation diagrams, the absorption effect is equivalent. If the high voltage drop when the diode is turned on is not considered, the absorption can be considered complete. After the test, you should be surprised that the diode can be chip mounted (fast switching diode, 1N4148 is good if the parameters are appropriate), and the resistance and capacitance can be chip mounted. The RCD absorption design here can be considered as follows: in order to absorb the oscillation peak, C should have enough capacity. After absorbing the peak energy, the voltage on the capacitor will not be too high. In order to balance the energy on the capacitor, the resistance R needs to consume the leakage inductance energy stored in the capacitor C, so the ideal parameter configuration is, The energy consumed by the resistance is just equal to the energy in the leakage inductance peak (at this time, the voltage at the C terminal of the capacitor is just equal to Uin/N+Uo). Because there are many uncertainties in the leakage inductance peak energy, the calculation method is difficult to work, so an experimental method is introduced below to design 1. Select a larger capacitance (such as 100nF) as the capacitor C, and D select an ultra fast recovery diode (such as 1N4148) that can withstand voltage>1.5 (Uin/N+Uo) ; 2. A smaller resistance of 10K and 1W can be selected as the absorption R; 3. Gradually increase the load, and observe the capacitor terminal C voltage and rectifier tube peak voltage: if the voltage ripple on C is greater than 20% of the average value, increase the value of C; If the voltage at the C terminal is too much higher than Uin/N+Uo (more than 20%, depending on the withstand voltage of the rectifier tube) under full load, the absorption is too weak, and the resistance R needs to be reduced; If the voltage on C is lower than or equal to Uin/N+Uo under full load, it means that the absorption is too strong, and the resistance R needs to be increased; If the voltage on C is slightly higher than Uin/N+U under full load

Summary: Rectifier diode It is a semiconductor device that converts AC power into DC power. Usually, it contains a PN junction, with anode and cathode terminals, and has obvious unidirectional conductivity. It can be made of semiconductor materials such as germanium or silicon, and is mainly used in various low-frequency rectifier circuits. In this paper, the civil aviation access network power supply transformation project Rectifier diode And an application example of. 0 Introduction In the naming of Huawei HONET series product FAl6 used in the access network of Zhongnan Civil Aviation, FA means flexible access, while 16 means that up to 16 2 Mbps channel signals can be connected externally. Through the FAl6 network, the radar signals, external VHF signals, PAE monitoring signals and video monitoring signals of six central and southern provinces (including Hainan, Guangdong, Hunan, Hubei, Guangxi and Henan) can all converge in Guangzhou. So as to provide services for Guangzhou Regional Control Center to command high-altitude flights in 6 provinces. The top frame of civil aviation FAl6 cabinet is a power rectifier module. The rectifier module can be powered by UPS power supply (220 V), and then the module provides DC - 48 V (measured as - 56.5 V) to power the FAl6 equipment. 1. There is a problem with the power supply of the access network. There are three terminals at the bottom of the FAl6 cabinet, two of which are grounding terminals, and one of which is an external power supply access terminal. Figure 1 shows the power supply schematic diagram of the FAl6 system. At point C in Figure l, a - 48 V power supply can be introduced to enable the internal power module and external power supply of FAl6 to supply power at the same time. In this way, even if one power supply is interrupted, the normal use of FAl6 will not be affected. However, due to limited conditions, the UPS+C point battery pack is currently used at each FAl6 station for two-way power supply, while the direct use of the battery pack to supply power to the FAl6 system has many hazards. First, the battery pack must be regularly discharged for maintenance. During the discharge process, the AC UPS input of the FAl6 cabinet needs to be cut off, so that during the discharge process, the AC UPS input of the FAl6 cabinet needs to be cut off. The abnormal phenomenon of the battery (such as the avalanche drop of the output voltage caused by the sudden rise of the internal resistance of the battery) will cause the interruption of the power supply of the entire cabinet; Second, this method lacks the ability to

The rectifier circuit shown in Figure 1 is broken during use, and the filter capacitor smokes. Further inspection found that the rectifier bridge was seriously heated. Since its pins were cut short and installed close to the printing plate, the surrounding printing plates had become burnt yellow. 1. Cause In the circuit in Figure 1, D1 and D3 are on when the AC is in the positive half cycle; D2 and D4 are on during negative half cycle; The rectifier current passes through two diodes at the same time. Because ordinary Rectifier diode The forward voltage drop of is about Iv, so the voltage drop on the rectifier bridge is about 2V If the output current of the rectifier bridge is 1.5A, the loss of the rectifier bridge is about 3W, It can be seen that the heat dissipation of the rectifier bridge itself should be considered. If the rectifier bridge is close to the printing plate and is too close to the peripheral components (such as filter capacitors), and its heat cannot be effectively dissipated, it may be overheated and damaged. 2. Countermeasures: Do not cut the pin of heating element too short, and make the bottom of the pin hang between the printing plate; At the same time, increase the spacing with the surrounding components. As shown in Figure 20 and Figure 3, the relationship curve between the lead length of the rectifier bridge stack (S2VB20) and the passing current is shown. It can be seen that the shorter the lead, the smaller the allowable passing current. In addition, the Schottky barrier diode (SBD) rectifier with small forward voltage drop has a voltage drop of only 0.5V, which can reduce the loss and heat generation. Compiled by Chengdu Qinghua

Inspection and analysis: a cygnet HY-U 19 electromagnetic cooker, the indicator does not flash after power on, and D4 (RF107) in the main board circuit was found during inspection Rectifier diode After breakdown, the mounting plates of the two poles had serious burning marks, and no abnormality was found in other components. Try D4 (RF107) Rectifier diode After replacement, the electromagnetic cooker resumed working, but after working for a few minutes, D4 (RF107) Rectifier diode It is damaged by breakdown again. Therefore, there is a hidden fault in the main board circuit. In this type of electromagnetic cooker, D4 (RF107) is mainly used for ten 18V low-voltage rectification, but it also has the function of short circuit protection (relevant local circuits are shown in the attached figure). After D4 (RF107) is replaced again and powered on for a short time, it is found that the surface temperature of D4 is high, which may be because the current passing through D4 exceeds the set value, but the main factor affecting the rise of D4 rectification current should be the oscillation timing circuit. Therefore, it is judged that C3 (1nF) timing capacitor is poor, and the fault is completely eliminated after its replacement. Summary: In the attached figure, C3 and R6 form a series RC constant timing circuit, which, together with U1 (13005), T1, D4, Q1, R4, R5, etc., forms a self-excited parallel switching power supply circuit. The working principle is as follows: 1. Self excitation oscillation In the attached figure, the primary windings of U1, T1, R4, R5, C3, R6, etc. form a self excitation oscillation circuit. When the city network voltage (AC220V) and the full bridge rectifier circuit are connected, a voltage of+300V is formed and passes through D11 and R102. The primary winding of Tl is added to the collector of U1 (13005). At the same time, the voltage of+300V is added to the base of U1 (13005) through R4 and R5 starting resistance, so that U1 (13005) starts to be connected. There is current passing through T1 primary winding and an upper positive and lower negative induced electromotive force is formed, Under the mutual inductance effect of T1 transformer, the secondary winding also has induced electromotive force, whose polarity is negative at the top and positive at the bottom. This potential is fed back to the base of U1 (13005) through R6 and C3, making U1 saturated and conductive quickly. When U1 is saturated and turned on, its collector current no longer increases, and T1 primary potential polarity changes and turns on

Royal Philips Electronics released MEGA Schottky Rectifier diode New products help mobile communication and consumer electronics manufacturers in Asia to produce smaller and more functional equipment. These more compact designs are realized by Philips's new compact and efficient rectifier with compact flat lead SOD323F package. Compared with the industry standard SMA package, these MEGA schottky rectifiers are 75% smaller in size and 60% more efficient than the MEGA schottky rectifiers packaged with Philips SOD323. These rectifiers are ideal for power management applications. They can improve performance, extend battery life, and reduce the size of the motherboard. These are the characteristics required for products such as mobile phones and digital cameras. Asian companies are the world's leading manufacturers of such products. The main obstacle to improve the overall electrical efficiency and reduce the package size is still the power consumption caused by the reduction of forward voltage. The heat generated by power consumption causes the package volume to be much larger than the silicon chip, so as to drain the heat out of the chip and prevent damage to the device. The thermal channel of Philips compact SOD323F flat lead package is shorter than that of SOD323 double wing package, and the lead frame material used is thicker, which greatly reduces the thermal resistance of the package. Therefore, compared with other Schottky rectifiers, the current input and output capacity of MEGA Schottky rectifiers of SOD323F is 50% higher, and the operating temperature is also higher, providing design engineers in Asia with more flexible design and reducing the size of the main board. Achim Engelhardt, marketing manager of Philips semiconductor diode products, said, "We live in a world where mobile communications and consumer goods are growing rapidly. For example, the average annual growth rate of the digital camera market is 30% (source: i

This compact SOD323F flat pin package has shorter thermal channel than the SOD323 wing package, and uses thicker wire frame materials to reduce the thermal resistance of the package, so that the current capacity of MEGA Schottky rectifier packaged with SOD323F is 50% higher than other Schottky products, and can work at higher temperatures, providing designers with greater design flexibility, And the required circuit board space is reduced. The size of these rectifiers is only 1.7 × 1.25 × 0.7mm, which is suitable for power management products to improve performance, extend battery life, and reduce the space occupied in mobile phones, digital cameras and other portable products.

New series 100V trench Schottky Rectifier diode Advanced trench technology is adopted, which can reduce the forward voltage drop of the diode when it is turned on, and reduce the reverse recovery time. This performance improvement can bring higher system efficiency, especially in high-frequency switching applications, such as switching power supply, ADXL213AE inverter, DC-DC converter, solar inverter and electric vehicle charging system. Schottky diodes are favored for their fast switching speed and low forward voltage drop. The new series of products further optimize these characteristics, making the rectifier generate less heat during operation, and improving energy efficiency.

Fast recovery diode and Rectifier diode Although they can be used interchangeably in some applications, there are some differences in their characteristics and scope of application. First, let's look at fast recovery diodes and Rectifier diode Basic characteristics of. Fast Recovery Diode is a diode with fast recovery time. Its main characteristics are low recovery time and low recovery voltage, and it can work at high frequencies. Fast recovery diodes are usually used for applications requiring fast switching and recovery, such as power switches, inverters, motor drive circuits, etc. Rectifier diode (Rectifier Diode) is a diode used to convert alternating current into direct current. Its main characteristics are high conduction current and high reverse breakdown voltage. Rectifier diode It is usually used in applications such as power supply, rectifier circuit and power filter, where AC power needs to be converted into DC power. Although fast recovery diodes and Rectifier diode They have similar characteristics in some aspects, but they are different in the following aspects: 1. Recovery time: fast recovery diodes have fast recovery time, usually in the range of several nanoseconds to tens of nanoseconds. and Rectifier diode The recovery time of is usually in the range of several hundred nanoseconds to several microseconds. Therefore, fast recovery diodes are more suitable for high frequency applications requiring fast switching and recovery. 2. Reverse recovery voltage: fast recovery diode has a small reverse recovery voltage, usually in the range of tens to hundreds of volts. and Rectifier diode The reverse recovery voltage of is usually in the range of several hundred volts to several thousand volts. Therefore, in high-pressure applications, Rectifier diode More applicable. 3. On current: Rectifier diode Generally, it has large current carrying capacity and can withstand high current. However, the fast recovery diode has a relatively small current carrying capacity. Therefore, in high current applications, Rectifier diode More applicable. To sum up, although the fast recovery diode and Rectifier diode In some applications, they can be used interchangeably, but their specific characteristics and application requirements need to be considered when selecting. If high frequency application of fast switching and recovery is required, or there is a difference between reverse recovery voltage and conduction current

Rectifier diode The main function in electronic circuits is to convert alternating current into direct current. AC is a current with alternating positive and negative voltages, while DC is a current with constant voltage. Rectifier diode Through its special electron flow mechanism, it can realize the rectification of alternating current. Rectifier diode The working principle of the PN junction is based on the characteristics of the PN junction. PN junction is composed of P-type semiconductor and N-type semiconductor. P-type semiconductors have positively charged holes and N-type semiconductors have negatively charged electrons. When P-type semiconductor and N-type semiconductor are connected together, a PN junction is formed. A depletion layer is formed near the PN junction, in which there are no free moving electrons and holes. When the P terminal of the PN junction is connected to a positive voltage and the N terminal is connected to a negative voltage, the width of the depletion layer will increase, resulting in the accumulation of electrons and holes in the depletion layer. This will result in the formation of a high electric field region called a potential barrier. The barrier blocks the free movement of electrons and holes. When the positive period of AC comes, its voltage exceeds the voltage of the barrier, and electrons and holes overcome the barrier and begin to move in the depletion layer. In this way, the current can flow Rectifier diode 。 However, when the negative period of AC comes, its voltage is lower than the voltage of the potential barrier, which blocks the movement of electrons and holes, thus preventing the flow of current. So, Rectifier diode The current is only allowed to pass in one direction, thus realizing the conversion from AC to DC. Rectifier diode Its main application in electronic circuit is as SN74AVC2T245RSWR rectifier. It can convert AC power supply into DC power supply to supply DC power required by electronic equipment. Common rectifying circuits include half wave rectifying circuit and full wave rectifying circuit. Half wave rectification circuit uses one Rectifier diode Pass the positive cycle of the AC power supply and block the negative cycle. In this way, the output current only contains the positive cycle part, which is an unstable DC current. Full wave rectification circuit uses two Rectifier diode , respectively pass the positive cycle and negative cycle of the AC power supply. In this way, the output current contains positive and negative periods, forming a relatively stable DC current. In addition, Rectifier diode It can also be used for voltage regulation and protection circuit. On

Ensure that the anode is connected to the positive pole in the circuit and the cathode is connected to the negative pole in the circuit. 5. How to determine Rectifier diode Maximum forward voltage and current? Rectifier diode The maximum forward voltage and current of are usually given in the specification or data manual. Ensure that the maximum forward voltage and current of the selected replacement diode are higher than the original diode. 6. How to judge Rectifier diode Is it damaged?

Recently, according to foreign media reports, STMicroelectronics (ST for short) launched a new high-voltage Schottky that will help improve the efficiency and robustness of telecommunications base stations, welding machines and other equipment Rectifier diode 。 New 200V power Schottky Rectifier diode The STPS60SM200C is targeted at the high current AC/DC power supply with a rated DC output of 30-50V. The maximum reverse voltage of 200V is compatible with the worst operating (packaging) environment at present. The design safety factor can withstand overvoltage and has a minimum operating temperature of - 40 ° C. Therefore, it is very suitable for distributing telecom base stations in any region of the world. As one of the few 200V Schottky diodes in the market, the STPS60SM200C integrates two interconnection diodes in a three pin package, which has higher efficiency and can replace the ultra-high speed diode with high on state loss. In today's base station design, the utilization rate of the traditional ultra high-speed diode still reaches about 30%. Therefore, STC expects that this new diode will be applied in a large scale, providing a new product option for high-end platform manufacturers currently using Schottky diodes. STPS60SM200C adopts the unique manufacturing technology of STPS60SM200C, and its electrostatic discharge (ESD) protection capability exceeds 2kV. Tested according to IEC 61000-4-2 standard, its ESD protection capability is higher than that of similar Schottky diodes in the market. This protection function can improve the survivability of new products against destructive security threats (such as transient high voltage), thus greatly reducing the downtime of equipment and minimizing the maintenance cost of equipment. Because installing mobile communication base stations in remote areas is time-consuming and expensive, these advantages are particularly important for mobile base station applications. Main features of STPS60SM200C: ·Repeated reverse peak voltage (VRRM): 200V ·Average forward current (IF (AV)): 2 x 30A ·Maximum working junction temperature (Tj (max)): 175 ° C ·Typical forward voltage (VF): 640mV STPS60SM200C adopts industrial standards

Rectifier diode The diode that rectifies the AC power supply into DC current is called Rectifier diode It is a surface bonding power device, and its operating frequency is low because of the large junction capacitance. Generally, the diode with IF above 1 A is encapsulated in a metal shell to facilitate heat dissipation; All plastic packaging is adopted for IF below 1 ampere. Due to the continuous improvement of modern technology, there are many high-power pipes in foreign countries, which also adopt plastic packaging.

ROHM Co., Ltd. (our company: Kyoto, Japan), a semiconductor manufacturer of "RR255M-400" for the discharge circuit of DSC flash lamps, has developed a subminiature type suitable for the discharge circuit of DSC flash lamps and other flash lamps Rectifier diode "RR255M-400" (sample price is 3.5 yuan/piece), and the scale of monthly production of 1 million pieces has realized mass production. The preliminary process is completed in ROHMWAKODEVICE (Rioka City, Okayama Prefecture, Japan); The later process is completed in ROHMWAKO (Rioka City, Okayama Prefecture, Japan). Today, with the development of miniaturization and thinness of DSC and other products, the requirements for reducing the size and installation area of parts are also increasing. The surge strength of the "RR255M-400" developed by ROHM is 40% higher than that of the traditional structure due to the unique high voltage withstand technology and the most suitable materials. And used as the world's smallest 2616 flash Rectifier diode While greatly realizing the miniaturization of packaging, it also reduces the installation area to 55% of the original, with various excellent features. The main features of the RR255M-400 are as follows: 1) It is packaged in 2616 specification, which reduces the thickness by 20% and the volume by 35% compared with the original product. 2) The installation area is 55% smaller than that of traditional products. 3) While realizing small package, it maintains 150A surge strength equal to that of traditional products. ROHM diode has always adopted unique design technology, component technology and self-developed production technology, striving to be the first to develop products that meet market needs. In the future, we will base on the position of customers and take the miniaturization, portability and energy saving of the whole machine as the production and development policy. [Explanation] Rectifier diode A diode that converts AC to DC and acts as a rectifier. The maximum value of the forward current of the surge strength (non return current). Flashlamp discharge circuit The so-called flashlamp discharge circuit generates alternating current through transistors and converts it into high-voltage alternating current through transformers. Then, these high-voltage alternating current flows through Rectifier diode It is converted into HVDC, which is accumulated in sequence

Royal Philips Electronics released MEGA Schottky Rectifier diode New products help mobile communication and consumer electronics manufacturers in Asia to produce smaller and more functional equipment. These more compact designs are realized by Philips's new compact and efficient rectifier with compact flat lead SOD323F package. Compared with the industry standard SMA package, these MEGA schottky rectifiers are 75% smaller in size and 60% more efficient than the MEGA schottky rectifiers packaged with Philips SOD323. These rectifiers are ideal for power management applications. They can improve performance, extend battery life, and reduce the size of the motherboard. These are the characteristics required for products such as mobile phones and digital cameras. Asian companies are the world's leading manufacturers of such products. The main obstacle to improve the overall electrical efficiency and reduce the package size is still the power consumption caused by the reduction of forward voltage. The heat generated by power consumption causes the package volume to be much larger than the silicon chip, so as to drain the heat out of the chip and prevent damage to the device. The thermal channel of Philips compact SOD323F flat lead package is shorter than that of SOD323 double wing package, and the lead frame material used is thicker, which greatly reduces the thermal resistance of the package. Therefore, compared with other Schottky rectifiers, the current input and output capacity of MEGA Schottky rectifiers of SOD323F is 50% higher, and the operating temperature is also higher, providing design engineers in Asia with more flexible design and reducing the size of the main board. Achim Engelhardt, marketing manager of Philips semiconductor diode products, said: "We live in a world where mobile communications and consumer goods are growing rapidly. For example, the average annual growth rate of the digital camera market is 30% (source: iSuppli, 2004). Philips MEGA Schottky rectifier new products combine the SOD323F package with Philips MEGA Schottky rectifier technology, so that designers can meet the market demand with a longer and smaller battery life design. " Philips' SOD323F is compact and compact, with a volume of only 1.7 mm × 1.25 mm

Sanken Electric recently developed a new type of "FMXJ series" Rectifier diode The reverse recovery time (the time to release the accumulated charge when the voltage is applied from forward to reverse) is 18 ns, which is more than 40% shorter than the original product of the company. The supply of samples began on September 15, 2005. The reverse recovery time has reached the "highest level in the world" (Sanken Electric). It is mainly aimed at driving circuit of PDP TV. In the field of PDP TV, the industry is currently stepping up the high-efficiency development aimed at reducing power consumption and low-noise development aimed at improving the image quality. For this reason, for the Rectifier diode , in order to reduce power loss, it is required to shorten reverse recovery time, and reduce Rectifier diode The demand for self noise is increasing. According to the relationship between reverse recovery time and noise, when the former is shortened, the latter will increase Rectifier diode The structure of is improved. A structure called "junction barrier schottky" is adopted, and a "schottky diode" structure that can effectively reduce noise is added to the "pn junction" structure, and the two structures are collocated side by side. Thus, low noise is achieved. At the same time, the reverse recovery time is improved by optimizing the "survival time control technology", which can shorten the disappearance time of a few potential barriers when the reverse voltage is applied. FMXJ series has three models: "FMXJ-1103S", "FMXJ-1104S" and "FMXJ-2164S". The withstand voltage and average forward current of the three are 300V and 10A, 400V and 10A, 400V and 16A respectively. TO-220F package is adopted for all. The sample price is 240 yen, 260 yen and 300 yen respectively. (Reporter: Okuboko)
