Description of pin and circuit diagram
The pin configuration of FQP5P10 is as follows (take TO-220 package as an example):
-Pin 1 (Gate, G): used to control the switch status of MOSFET. It can be turned on or off by applying positive or negative voltage. -Pin 2 (Drain, D): Absorb the current from the load and connect it to the high end of the power supply or load. -Pin 3 (Source, S): connected to the negative pole of the power supply, usually the ground wire, and the current flowing through the source pole will be led to the load.
In the circuit diagram, FQP5P10 can be used as the key component of the low side switch to control the on-off of the load. Applying voltage through the grid can effectively control the start and stop of the load. In addition, FQP5P10 can withstand high current and voltage fluctuations, making it play an important role in the design of motor drivers and switching power supplies.
