Specifications: The APY226S is a high-voltage PhotoMOS SSR in an SOP-4 package. It is a 1 Form A (SPST-NO) relay rated for 150mA 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: Suited for switching low-current loads at very high voltages. Ideal for applications such as CRT anode voltage switching, neon sign control, electrostatic precipitator circuits, high-voltage power supply output control, and test equipment requiring isolation and switching at several hundred volts, all in a compact, industry-standard SOP package.
