An electronic circuit element consisting of a controlled diode or solid-state switch. The diode is usually turned ‘‘on’’ by a small voltage from an external circuit and turned ‘‘off’’ when the voltage is reversed. Used to switch large currents in IP transmitters. When the semiconductor is silicon, a controlled rectifier is called SCR. A GTO (gate turn-off switch) controlled rectifier can be turned on and off independently of the current through the diode.
