MOC3051SR2VM Description

Short technical summary and product information.

The ON Semiconductor MOC3051SR2VM is a 6-pin DIP random-phase triac driver optocoupler with a 600 Volt peak blocking voltage. It consists of a GaAs infrared emitting diode optically coupled to a non-zero-crossing silicon bilateral AC switch (triac). This device is designed to isolate low voltage logic from 115 V AC and 240 V AC lines, enabling random phase control of high current triacs or thyristors. It features greatly enhanced static dv/dt capability for stable switching performance with inductive loads.

 

Key electrical specifications include a 600V peak blocking voltage and a 15mA current rating. The optocoupler provides 4,170Vrms isolation per UL1577 and meets DIN EN/IEC60747-5-5 standards. It operates within a temperature range of -40°C to 85°C.

 

The MOC3051SR2VM is housed in a 6-SMD, Gull Wing package, suitable for surface mounting. Typical applications include solenoid/valve controls, lamp ballasts, static AC power switches, interfacing microprocessors to AC peripherals, solid-state relays, incandescent lamp dimmers, temperature controls, and motor controls.
