AQW212EHAZ is a PhotoMOS relay featuring reinforced insulation rated at 5,000 Vrms, packaged in a DIP8-pin configuration with a 2 Form A output structure. The device is applicable for both 2 Form A use and two independent 1 Form A configurations, making it versatile for various switching applications. It delivers a continuous load current of 0.5 A at 60 V peak AC (or 0.6 A when using a single channel), with an on-resistance of 0.83 O typical at 5 mA LED current and a maximum off-state leakage current of 1 µA. The relay exhibits high-speed response characteristics with a typical turn-on time of 4 ms and turn-off time of 0.08 ms, operating reliably across the temperature range of -40°C to +85°C. Common applications include modem switching, telephone equipment, industrial plant control, security systems, and sensing equipment where low-level signal isolation and fast switching are required.
