The MOC3021SR2VM is a 6-pin DIP Random-phase Optoisolator optically isolated TRIAC driver devices. This device contains a GaAs infrared emitting diode and a light activated silicon bilateral switch, which functions like a TRIAC. It is designed for interfacing between electronic controls and power TRIACs to control resistive and inductive loads for 115VAC operations. It is also suitable for solenoid/valve controls, traffic lights, static AC power switch, vending machines, incandescent lamp dimmers and solid state relay.
Excellent IFT stability - IR emitting diode has low degradation
