silicon-controlled rectifier

n
(Electronics) a semiconductor rectifier whose forward current between two electrodes, the anode and cathode, is initiated by means of a signal applied to a third electrode, the gate. The current subsequently becomes independent of the signal. It is a type of thyristor. Abbreviation: SCR
