AQW212EHA is a DIP8-pin PhotoMOS relay featuring reinforced insulation rated at 5,000 Vrms, designed for 2 Form A or dual independent 1 Form A switching configurations in AC/DC dual-use applications. The device delivers a continuous load current of 0.5 A at 60 V peak AC (or 0.6 A when using a single channel), with a maximum peak load current of 1.5 A. It exhibits low-level off-state leakage current of maximum 1 µA, high sensitivity with LED operate current of 1.2 mA typical, and rapid response times with turn-on time of 4 ms typical and turn-off time of 0.08 ms typical. The relay operates reliably across an ambient temperature range of -40°C to +85°C and features an on-resistance of 0.83 O typical at 5 mA LED current. Common applications include modem switching, telephone equipment, industrial plant control, security systems, and sensing equipment where galvanic isolation and low-level signal control are essential.
