Specifications: The APY255G2S is a high-current, high-efficiency PhotoMOS SSR in a standard SOP-4 surface-mount package. It is a 1 Form A (SPST-NO) relay rated for 1.5A at 150V AC/DC. It features a very low 0.12Ω on-state resistance, provides 2500Vrms isolation, and switches with 1000μs (on) and 60μs (off) times. It operates from -40°C to 85℃ with a 1.2-1.5VDC input. Application Scenarios: Designed for high-efficiency medium-to-high current switching in a cost-effective, industry-standard package. Ideal for driving motors, solenoids, and high-power LEDs in appliances, power tools, industrial controls, and automotive applications. Its low Rds(on) minimizes heat generation, making it suitable for thermally challenging designs while the SOP package ensures easy manufacturability.
