The MOC3021SR2M is a single channel random-phase triac driver output optocoupler. It has designed for interfacing between electronic controls and power triacs to control resistive and inductive loads for 115 VAC operations.

This device contains a GaAs infrared emitting diode and a light activated silicon bilateral switch, which functions like a triac.

Features:

• High input-output isolation voltage
• Excellent IFT stability
• 400 V peak blocking voltage
• Operating temperature -40° C to +85° C

Applications:

• Solenoid/valve controls and industrial controls
• Traffic lights and static AC power switch
• Vending machines and motor control
• Incandescent lamp dimmers
• Solid state relay and lamp ballasts
