AQW214AX is a compact PhotoMOS relay designed for AC/DC dual-use applications with a 400V peak load voltage rating. The device features a miniature 8-pin DIP package measuring 6.4 × 9.78 × 3.9 mm with through-hole terminals, supporting a continuous load current of 100mA (130mA peak in single-channel mode) and a maximum peak load current of 0.3A. It incorporates an integrated LED input with typical operating current of 0.9mA to 3mA, extremely low off-state leakage current of maximum 1µA, and fast switching response with typical turn-on time of 0.28ms. The relay is applicable for 2 Form A use or two independent 1 Form A configurations, enabling control of low-level analog signals without distortion due to its low closed-circuit offset voltage. Common applications include high-speed inspection machines, telecommunications equipment, and computer control systems requiring reliable solid-state switching.
