An SCR, or Silicon Controlled Rectifier, is a semiconductor, or integrated circuit (IC), that allows the control of current using a small current. Basically, it is a simple direct current (DC) light switch.. SCR: Silicon Controlled Rectifier. A semiconductor device that functions as an electrically controlled switch.
