Specifications: The APY211G2HS is a high-current, fast-turn-off PhotoMOS SSR rated for 2.5A at 40V (AC/DC) in SOP-4. It has a low 60mΩ on-state resistance, 2500Vrms isolation, and switching times of 800μs (on) and a very fast 20μs (off). It operates from -40°C to 85°C with 1.2-1.4VDC input.

Application Scenarios: Combines high current capability with rapid disconnection. Suitable for applications requiring quick shutdown for safety or control, such as in motor brake circuits, fast over-current protection crowbars, and high-speed load switching in power sequencing or test equipment.
