MOC3081M Zero-Cross Triac Driver Optocoupler IC – DIP-6

Description

The MOC3081M is a high-performance optocoupler IC featuring a Gallium Arsenide (GaAs) infrared-emitting diode optically coupled to a monolithic silicon detector that functions as a zero-voltage crossing bilateral triac driver. It is specifically engineered to provide a robust interface between low-voltage control logic and high-power equipment powered by 240 VAC lines.

By ensuring that switching occurs only when the AC voltage passes through the zero-crossing point, the MOC3081M significantly minimizes conducted and radiated electromagnetic interference (EMI). With an 800V peak blocking voltage and superior static dv/dt capability, this device is the ideal solution for controlling sensitive high-current AC loads, such as motors, solenoids, and heating elements, while protecting your control logic from high-voltage transients.
