A solid state device that has bistable electrical characteristics. Three common thyristor devices are diacs, silicon-controlled-rectifiers (SCRs) and triacs.
electronic switch without moving parts.
Type of rectifier, an electronic device that conducts electricity in one direction only. The thyristor is composed of layers of semiconductor material sandwiched between two electrodes called the anode and cathode. The current can be switched on by using a third electrode called the gate.
Thyristors are used to control mains-driven motors and in lighting dimmer controls.
