Specifications: The APY153G1S is a high-voltage, medium-current PhotoMOS SSR in an SOP-4 package. It is a 1 Form A (SPST-NO) relay rated for 1.0A at 360V AC/DC. It features a low 0.8Ω on-state resistance, provides 2500Vrms isolation, and switches with 1800μs (on) and a fast 30μs (off) time. It operates from -40°C to 85℃ with a 1.16-1.32VDC control input. Application Scenarios: Suited for switching medium-power loads at high line voltages. Common applications include appliance motor control (e.g., for washers, dryers), industrial actuator and contactor drives, solid-state lighting ballasts, power supply output control, and as a reliable AC switch in industrial and consumer equipment, offering a balance of voltage rating, current capability, and cost in a standard package.
