Specifications: The APV217E is the through-hole DIP-6 version of a versatile PhotoMOS SSR. It is a 1 Form A (SPST-NO) relay rated for 200mA load current and 200V load voltage (AC/DC). It features a 5Ω on-state resistance, 5000Vrms isolation, and switching times of 400μs (turn-on) and 50μs (turn-off). It operates from -40°C to 85℃ with a 1.2-1.4VDC input. Application Scenarios: A general-purpose through-hole relay for medium-voltage switching. Suitable for industrial control system I/O cards, data acquisition systems, test equipment channel switching, medical device patient isolation circuits, and as a reliable interface in power over Ethernet (PoE) equipment, offering robust performance and the serviceability of a DIP package.
