The AQV214EHA is a reinforced insulation PhotoMOS relay designed for AC load switching with enhanced isolation capabilities. It features a 5,000V AC I/O isolation voltage (reinforced type) and is rated for 400V peak AC load voltage with a continuous load current of 120 mA, making it suitable for controlling moderate-power AC circuits. The device exhibits extremely low closed circuit offset voltage enabling control of low-level analog signals without distortion, combined with stable on-resistance and a maximum off-state leakage current of 1 µA. With a DIP6-pin package configuration and operating temperature range of -40°C to +85°C, the AQV214EHA is ideal for high-speed inspection machines, telephone equipment, data communication systems, and computer applications requiring reliable galvanic isolation and low-level signal control.
