MOC3063 – Zero-Cross Optocoupler Triac Driver

Description

The MOC3063 is an optically-isolated triac driver designed for safe and reliable interfacing between low-voltage control circuits (like microcontrollers, Arduino, ESP32, or Raspberry Pi) and high-voltage AC loads. With built-in zero-cross detection, it reduces electrical noise and provides smoother switching, making it ideal for dimmers, motor speed control, and other AC power applications.
