MOC3042 Zero-Cross Optoisolator Triac Driver 6 Pin
The MOC3042 Zero-Cross Optoisolators Triac Driver 6 Pin is a zero-cross optoisolator triac driver this Meaning it has a Infra-red Light Emitting Diode (LED) inside it coupled with a TRIAC. When the LED is triggered the TRIAC is also turned on and designed for interfacing low-voltage control circuits with high-voltage AC loads. It integrates a gallium arsenide infrared emitting diode (IRED) that optically triggers a silicon bilateral switch triac, providing safe electrical isolation between input and output. The zero-crossing feature ensures switching occurs only when the AC load voltage is near zero, minimizing electrical noise, reducing inrush current, and improving overall system reliability. Packaged in a compact 6-pin DIP, the MOC3042 is widely used in AC load switching, solid-state relays, lamp dimmers, and motor control applications, offering high safety and efficient performance in industrial and consumer electronics.
Features
- Zero-crossing triac driver for low noise switching.
- High isolation voltage between input and output (typically 7500 Vrms).
- Input LED trigger current as low as 15 mA.
- Compact 6-pin DIP package for easy PCB mounting.
- Provides 5 kV to 7.5 kV isolation resistance.
- Designed for interfacing logic level signals to AC loads.
- High static dv/dt immunity for reliable operation.
- Suitable for 115/230 VAC line switching applications.
- Low power triggering with efficient optocoupler design.
- UL and VDE recognized for safety compliance.
