Welcome to the Thyristor!
A thyristor is a solid-state semiconductor device with four layers of alternating P- and N-type materials. It acts exclusively as a bistable switch, conducting when the gate receives a current trigger, and continuing to conduct until the voltage across the device is reversed biased, or until the voltage is removed (by some other means). Some sources define silicon-controlled rectifier (SCR) and thyristor as synonymous. Other sources define thyristors as more ornately constructed devices that incorporate at least four layers of alternating N-type and P-type substrate.

Ⅰ OverviewThyristor, commonly known as silicon controlled rectifier(SCR), its normative term is reverse blocking three-terminal thyristor. Thyristors are high-power semiconductor devices that have both switching and rectifying functions, and are used in various circuits such as controllable rec...
