Thyristors are a family of four-layer semiconductor devices that act as electronic switches, allowing current to flow in one direction only, and can be used to control and regulate larger currents, AC and DC voltages. A Thyristor is a type of electrical switch whose state, once set, will remain until the switch is turned off or it is triggered to turn on again. The T72H0835B4DN is a Thyristor-SCR (silicon controlled rectifier) that has a wide range of applications, and this article explains the working principle and application fields of this device.

Working Principle:

An SCR consists of four elements; an anode, a cathode, a gate and an internal resistor. All these elements are connected together to form a semiconductor diode where current can flow from the anode to the cathode. In case the voltage across the SCR exceeds the pre-set threshold, it will turn on and become conductive. The current starts flowing from the anode to the cathode. When the current exceeds the trigger current required, the thyristor will switch on and remain in that state until the current turns off or the device is triggered to turn off.

Application Field:

T72H0835B4DN is a type of SCR that is commonly used in a variety of applications. It is commonly used in power switching, motor control, lamp control, and arc welding, among others.
