Specifications: The APY236S is a high-voltage, low-current PhotoMOS SSR in an SOP-4 package. It is a 1 Form A (SPST-NO) relay rated for 100mA at 650V AC/DC. It has a 15Ω on-state resistance, provides 2500Vrms isolation, and switches with 150μs (on) and 20μs (off) times. It operates from -40°C to 85℃ with 1.2-1.4VDC control. Application Scenarios: Designed for isolated switching of high-voltage, low-current signals or supplies. Ideal for applications such as power supply monitoring and sequencing, industrial sensor interfaces, medical device auxiliary power control, solid-state relay driving, and as a component in test equipment for high-voltage circuits, provided in a standard, easy-to-assemble SOP package.
