Kyocera Corporation Datasheets for Silicon Controlled Rectifiers (SCR)

Silicon controlled rectifiers (SCR) are four-layer (PNPN) thyristors with three terminals: an input control terminal (gate), an output terminal (anode), and a terminal common to both the input and output (cathode). SCRs are used mainly with high voltages and currents, often to control alternating current (AC) where the change of sign causes the device to switch off automatically.
