AQH2223
Overview
The AQH2223 is a compact solid-state photo-coupled relay (photorelay) in an 8-DIP package designed for AC load switching up to 600V. It features zero-cross circuitry to minimize electrical noise during switching and can handle a continuous load current of 900 mA.
Why Choose This Part
The integrated zero-cross function reduces electromagnetic interference (EMI) and inrush current, extending the lifespan of connected loads. Its solid-state design eliminates contact bounce and mechanical wear, providing higher reliability than traditional electromechanical relays in high-cycle applications.
Applications
Key Specifications
Getting Started
Drive the input LED using a standard microcontroller GPIO through a current-limiting resistor to meet the 1.21V typical forward voltage requirement. Ensure adequate PCB copper area for the output pins to manage thermal dissipation when switching the maximum 900 mA load.
