Specifications: The APW217EH is a dual-channel (2 Form A) PhotoMOS SSR in an SMD-8 package. Each channel is a 1 Form A (SPST-NO) switch rated for 200mA load current and 200V load voltage (AC/DC). Each channel has a 5Ω on-state resistance, provides 5000Vrms isolation, and switches with 400μs (turn-on) and 50μs (turn-off) times. It operates from -40°C to 85℃ with a 1.2-1.4VDC input.

Application Scenarios: Ideal for applications needing two independent, medium-voltage signal or power switches in a compact surface-mount form. Typical uses include dual-channel isolation in data acquisition front-ends, switching sensor supplies in industrial systems, redundant control paths in safety-critical electronics, audio/video signal routing in broadcast and pro-AV gear, and as a versatile building block for isolated I/O in embedded systems and instrumentation.
