thyristor

Four-layer semiconductor

A thyristor is a semiconductor device that acts as a switch, conducting current in one direction once triggered by a small signal.

Unlike a simple switch, it stays on until the current drops below a threshold.

Thyristors control high-power applications like motor drives, light dimmers, and power supplies: The thyristor failed, killing the circuit.
