MOC3021M Datasheet PDF - ON Semiconductor

●The MOC3021-M from Fairchild is a through hole random phase triac driver output optocoupler in 6 pin DIP package. This device contains a GaAs infrared emitting diode and a light activated silicon bilateral switch which functions like a triac. This device is designed for interfacing between electronic controls and power triacs to control resistive and inductive loads for 115 VAC operation. Typical applications include industrial controls, solenoid/valve control, traffic lights, static AC power switch, vending machines, incandescent lamp dimmers, solid state relays and lamp ballasts.
