Specifications: The APW217E is a dual-channel (2 Form A) PhotoMOS SSR in a DIP-8 through-hole 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 switches with high isolation. Typical uses include dual-channel signal isolation in data acquisition systems, switching multiple sensor powers or signals in industrial controls, redundant control paths in safety systems, audio/video signal routing in broadcast equipment, and as a building block for multi-pole switching in prototyping and educational boards.
