Specifications: The APY272G2EH is the surface-mount SMD-4 version of a high-current PhotoMOS SSR with soft-start characteristics. It is a 1 Form A (SPST-NO) device rated for 2.0A at 60V AC/DC. It features a low 0.58Ω on-state resistance, provides 5000Vrms isolation, and has asymmetrical switching times: a slow 4800μs (4.8ms) turn-on and a 150μs turn-off. It operates from -40°C to 85℃ with a wider 1.0-1.4VDC input range. Application Scenarios: Designed for applications requiring controlled, soft turn-on in a compact package. Ideal for soft-start circuits in compact power supplies, inrush current limiting for capacitive loads or lamps, motor acceleration control in space-constrained designs, and any application where a gradual voltage rise is needed to protect sensitive load or source circuits, provided in a miniature SMD format.
