ONSEMI MOC3081M Triac Driver Optocoupler

The MOC3081-M is an 800V zero crossing TRIAC driver optocoupler. It features a gallium arsenide infrared LED optically coupled to a monolithic silicon detector, enabling it to function as a zero voltage crossing bilateral TRIAC driver. Designed for easy interfacing with discrete power TRIACs, it is suitable for controlling 240VAC loads such as solid-state relays and solenoids. The device simplifies the logic control of high-voltage AC power, provides zero voltage crossing switching, and offers a dv/dt of up to 1500 V/μs (typical) with a guaranteed minimum of 600 V/μs. It is compatible with the FKPF12N80 discrete power TRIAC.
