MPN:MOC3022

The MOC3022 is a triac-output optocoupler IC from Fairchild, designed for safe and reliable AC load switching and phase control. It features an infrared LED input optically coupled to a triac driver output, providing strong electrical isolation between low-voltage control circuits and high-voltage AC power lines.

As a random-phase optotriac, the MOC3022 is ideal for lamp dimmers, motor speed controllers, solid-state relays, and heater control circuits, where triggering at any point in the AC waveform is required.
