The MOC3021 Optoisolator Triac Driver IC DIP-6 is a widely used optoisolator with Triac driver output, designed for safe and reliable switching of AC loads. It features an infrared LED optically coupled to a light-activated triac in a compact 6-pin DIP package, enabling electrical isolation between low-voltage control circuitry and high-voltage AC circuits. Ideal for applications such as solid-state relays, light dimmers, motor control, and AC load switching, the MOC3021 ensures low power consumption and excellent noise immunity. This device provides non-zero-crossing turn-on, allowing it to switch the load at any point in the AC cycle, making it suitable for phase control applications.
