MOC3021 Optocoupler Triac Driver IC (DIP 6 Package)

The MOC3021 is an optically isolated triac driver IC designed to interface low voltage control circuits with AC power switching devices. It combines an infrared LED input with a photo triac output, providing electrical isolation between the control and AC power sections. Its random phase switching operation makes it suitable for phase control applications such as dimmers, heater controllers, and motor speed controls.
