Specifications: The APY230S is a medium-voltage PhotoMOS SSR in an SOP-4 package. It is a 1 Form A (SPST-NO) relay rated for 120mA at 350V AC/DC. It has a 17Ω on-state resistance, provides 2500Vrms isolation, and switches with 230μs (on) and 50μs (off) times. It operates from -40°C to 85℃ with 1.2-1.4VDC control. Application Scenarios: Designed for general-purpose switching of medium-voltage, low-current loads. Common applications include industrial sensor power isolation, small relay coil driving, power supply control, appliance auxiliary circuits, and as a reliable switch in vending machines and commercial equipment, providing a good balance of voltage rating, isolation, and cost in a standard package.
