Thyristor is a solid-state semiconductor device composed of four layers of alternating P- and N-type materials. It functions as a bistable switch, conducting current only when triggered by a gate signal, and remains conducting until the voltage across it drops below a certain threshold. Thyristors are widely used for controlling high-power electrical circuits, offering efficient and reliable performance in various industrial and electronic applications.
