SCR Output

OptocouplerTriac OutputAC Control

The MOC3021M is a random-phase triac-output optocoupler designed for AC load control, providing 5000Vrms isolation between logic and power circuits.

Best for

  • AC solenoid control
  • Motor speed control
  • Lamp dimming

Avoid if

  • Zero-crossing switching is required for noise reduction

Check before use

  • Ensure the load current does not exceed 100mA RMS without an external power triac.
