The AQY212EHAX is a PhotoMOS GE 1 Form A relay designed for AC/DC dual-use applications with reinforced insulation of 5,000 Vrms. It features a 60V peak load voltage rating with a continuous load current of 0.55A and peak load current of 1.5A (100 ms, 1 shot). The device operates with an LED forward current of 50 mA and exhibits low on-resistance characteristics across the -40°C to +85°C operating temperature range, with typical LED dropout voltage of 1.25V at 50 mA input current. The relay provides high sensitivity and low on-state leakage current (maximum 1 µA), making it suitable for controlling low-level analog signals in modem, telephone equipment, plant equipment, security systems, and sensing applications.
