MOC3011SR2M

Triac, SCR Output Optoisolators Overview

The MOC3011SR2M is a Triac and SCR output optocoupler manufactured by onsemi. It features a PhotoTriac output without a zero-crossing circuit, enabling random phase triggering for AC load control. The device utilizes a 6-SMD,鸥翼型 (gull-wing) surface-mount package with one channel. Key electrical parameters include a maximum forward current of 60 mA, a forward voltage of 1.15 V, and an isolation voltage of 4170 Vrms. It supports a peak repetitive off-state voltage of 250 V and operates within a temperature range of -40°C to +85°C.
