MOC3083FR2M

Triac, SCR Output Optoisolators Overview

The MOC3083FR2M is a Triac output optocoupler manufactured by onsemi, featuring an integrated zero-crossing circuit. It consists of an aluminum gallium arsenide infrared emitting diode optically coupled to a monolithic silicon detector that performs the zero-voltage crossing triac driver function. The device is housed in a 6-SMD Gull Wing package and supports surface-mount installation. Key electrical parameters include a maximum forward current of 60 mA, a peak off-state voltage of 800 V, and an isolation voltage rating of 7500 Vpk. It operates within a temperature range of -40°C to +85°C.
