    Description

    The PC814 SMD optocoupler IC is a reliable photocoupler / opto-isolator designed to provide electrical isolation between input and output circuits using light-based signal transfer. It helps protect sensitive low-voltage circuits from high-voltage spikes and noise, making it ideal for SMPS, relay boards, industrial control, and microcontroller interfacing.

    PC814 is widely used in power supply feedback circuits, signal isolation, automation boards, Arduino/ESP32 projects, and other electronics requiring safe isolation.

    Applications

    • Signal isolation for microcontrollers

    • SMPS feedback and control circuits

    • Relay and triac driver circuits

    • Industrial automation and control

    • Noise and surge protection

    • PLC interface circuits
