Specifications: The APY212R1S is a fast-switching PhotoMOS SSR for 120mA, 60V (AC/DC) loads. Housed in SOP-4, it has a 5Ω on-state resistance, 2500Vrms isolation, and fast 50μs/30μs switching. It operates from -40°C to 85°C with 1.2-1.4VDC input.

Application Scenarios: Suited for applications requiring fast response with lower current. Ideal for digital signal isolation, interfacing low-power sensors, driving small indicators or optocouplers, and as a high-speed switch in communication and control systems where response time is important.
