The MOC301XM and MOC302XM series are optically isolated triac driver devices. These devices contain a GaAs infrared emitting diode and a light activated silicon bilateral switch, which functions like a triac. They are designed for interfacing between electronic controls and power triacs to control resistive and inductive loads for 115 VAC operations.
The MOC301XM and MOC302XM series are optically isolated triac driver devices that contain a GaAs infrared emitting diode and a light‑activated silicon bilateral switch. They are intended for interfacing electronic controls with power triacs to switch resistive and inductive loads at 115 VAC.
Key features include high isolation voltage (minimum 5300 VAC RMS), peak blocking voltages of 250 V (MOC301XM) and 400 V (MOC302XM), and a maximum forward current of 60 mA. Typical applications cover industrial controls, solenoid/valve drives, traffic lights, static AC power switches, vending machines, lamp dimmers, solid‑state relays, motor control, and lamp ballasts.
