Specifications: The APW217S is a dual-channel (2 Form A) PhotoMOS SSR in an SOP-8 package. Each channel is a 1 Form A (SPST-NO) switch rated for 180mA 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: A robust dual-channel relay for medium-voltage switching. Common applications include isolated signal routing in industrial communication interfaces, dual-sensor power switching, safety interlock circuits, audio signal switching in professional equipment, and as a reliable interface in power over Ethernet (PoE) devices and other network equipment, providing two isolated channels in a standard, easy-to-assemble SOP package.
