MOC3022SVM

Triac, SCR Output Optoisolators Overview

The MOC3022SVM is a single-channel Triac output optocoupler manufactured by onsemi, designed for non-zero-crossing AC power control applications. It features a PhotoTriac output capable of switching up to 400 V with a maximum forward current of 60 mA and peak gate trigger current of 10 mA. The device provides high isolation voltage of 4170 Vrms and operates within a temperature range of -40°C to +85°C. Packaged in a compact 6-SMD surface-mount configuration, it ensures reliable signal transmission between low-voltage control circuits and high-voltage AC loads.
