Working Principle

The T72H1235B4DN is a type of thyristor, or Silicon Controlled Rectifier, that is designed for power control applications. Like other thyristors, it is made from a P-N-P-N structure of four layers, with each layer having a different electrical potential when forward-biased. When the device is triggered, the thyristor switches on and current is allowed to flow through the device.

The thyristor is triggered by applying a pulse of electrical current to the gate of the device. This pulse of current causes a reverse current to flow through the gate, which causes the thyristor to turn on and allow the current to flow through. The triggering current is typically applied with a gate driver which ensures the correct amount of current is applied to the device, and that it is applied at the correct speed.

The T72H1235B4DN also has built-in protection against surge, overcurrent, and thermal overload. This makes it suitable for use in a variety of power control applications.
