MOC3020X

Triac, SCR Output Optoisolators Overview

The MOC3020X is a six-pin optically coupled isolator featuring a gallium arsenide infrared emitting diode paired with a light-activated silicon bilateral triac. It provides electrical isolation without zero voltage crossing detection, enabling random phase control applications. The device supports a peak repetitive off-state voltage of 400V and offers an isolation voltage rating of 5300Vrms across one channel. Key electrical characteristics include a forward current maximum of 50mA, a typical forward voltage of 1.2V, and a triac turn-on current of 35mA. Operating temperature ranges from -40°C to 100°C.
