Specifications: The APY215G1EH is a compact, surface-mount PhotoMOS SSR in an SMD-4 package. It is a 1 Form A (SPST-NO) relay rated for 1.1A load current and 150V load voltage (AC/DC). It features a low 0.45Ω on-state resistance for minimal power loss, high 5000Vrms isolation voltage, and asymmetrical switching times of 1500μs (turn-on) and 80μs (turn-off). It operates from -40°C to 85°C with a 1.2-1.4VDC control input.

Application Scenarios: Perfect for space-constrained designs needing medium-current switching with high isolation. Common applications include industrial automation (PLC I/O modules, sensor interfaces), home appliance control boards (smart plugs, washing machines), telecommunications equipment for power or signal switching, and automotive electronics (e.g., body control modules, LED lighting drivers) where reliability, compact size, and electrical noise immunity are essential.
