The AQW210 is a compact PhotoMOS relay in an 8-pin DIP package designed for AC/DC dual-use applications with a 350V peak load voltage rating and 120 mA continuous load current capability. This device features extremely low closed-circuit on-resistance of 30 O (typical) to 50 O (maximum) and minimal off-state leakage current of 1 µA maximum, enabling precise control of low-level analog signals without distortion. The relay operates with a 5 mA input LED current, delivers fast switching response with typical turn-on time of 0.28 ms, and maintains reliable performance across an operating temperature range of -40°C to +85°C. Its compact dimensions of 6.4 mm width × 9.78 mm length × 3.9 mm height, combined with RoHS compliance and support for both 2 Form A or two independent 1 Form A configurations, make it ideal for high-speed inspection machines, telecommunications equipment, and computer control applications requiring reliable solid-state switching.
