MOC3031FR2M

Triac, SCR Output Optoisolators Overview

The MOC3031FR2M is a Triac and SCR output optocoupler manufactured by onsemi. It features a PhotoTriac output with an integrated zero-crossing circuit, designed for low electromagnetic interference switching. The device utilizes a 6-SMD Gull Wing surface-mount package and provides high isolation voltage of 7500 Vrms between input and output. Key electrical parameters include a maximum forward current of 60 mA, a peak off-state voltage of 250 V, and a maximum trigger current of 15 mA. It operates within a temperature range of -40°C to +85°C.
