Ps2501-4: Transistor Output Optocouplers Hi-Iso Photo 4-Ch – SCIx1315

The MOC3042 is a highly reliable optoisolator triac driver designed to provide zero-crossing detection and control for AC loads. Featuring a gallium arsenide infrared LED optically coupled to a silicon triac, this device is optimized for switching applications in industrial, consumer, and lighting systems.

With a 400V rated repetitive off-state voltage (VDRM) and high dv/dt immunity of 2000 V/µs, the MOC3042 ensures robust operation in demanding environments. The zero-crossing functionality minimizes electrical noise and extends the lifespan of the controlled load. Certified to UL standards, this optoisolator provides up to 7500 Vrms isolation, ensuring safety and reliability in critical applications.

Encased in a standard DIP-6 package, the MOC3042 is easy to integrate into various PCB designs, making it an ideal choice for engineers seeking a compact and efficient solution for AC load control.
