Features and Applications

The MOC3043SR2M is a single channel zero-cross triac driver output optocoupler. It has designed for use with a triac in the interface of logic systems to equipment powered from 115 VAC lines.

This device contains a GaAs infrared emitting diode optically coupled to a monolithic silicon detector performing the functions of a zero voltage crossing bilateral triac driver.


  • Simplifies logic control of 115 VAC power
  • Zero voltage crossing
  • Operating temperature -40° C to +85° C


  • Solenoid/valve controls and lighting controls
  • AC motor drives and static AC power switches
  • Temperature controls and E.M. contactors
  • Solid state relays and AC motor starters
