MOC3083 Zero-Cross Triac Driver Optoisolator IC – DIP-6

Description

The MOC3083 is a high-performance triac driver optoisolator designed to interface low-voltage control logic with 240 VAC power lines. It utilizes a Gallium Arsenide (GaAs) infrared-emitting diode optically coupled to a monolithic silicon detector that functions as a zero-voltage crossing bilateral triac driver.

By incorporating zero-voltage crossing technology, this device ensures that the load is energized only when the AC voltage is near zero, significantly minimizing conducted and radiated line noise. With an 800V peak blocking voltage and superior static dv/dt immunity, the MOC3083 is an ideal choice for driving discrete power triacs in industrial and consumer applications where switching stability and noise reduction are critical.
