Tyn616 is a unidirectional silicon controlled electronic component. SCR (silicon controlled rectifier) is the abbreviation of silicon controlled rectifier. There are several types of silicon controlled rectifier: unidirectional, bidirectional, turnoff and light control. It has the advantages of small size, light weight, high efficiency, long life, easy control, etc. It is widely used in various automatic control and high-power power conversion occasions such as controlled rectifier, voltage regulation, inverter and contactless switching.
