Specifications: Balancing current capacity with switching control, the APY212G1S is a 1.1A, 60V (AC/DC) PhotoMOS relay in SOP-4. It features a 0.13Ω on-state resistance and standard 2500Vrms isolation. Its switching profile includes a deliberate 1.3ms turn-on, useful for inrush limiting, and a 50μs turn-off. The component is specified for the full industrial temperature range (-40°C to 85°C) and uses a 1.2-1.4VDC control signal.

Application Scenarios: The controlled turn-on makes this relay suitable for applications with capacitive or incandescent loads. It is effectively used in soft-start circuits for power supplies, staged power-up sequences in embedded systems, and controlling small motors or lamps where a gradual voltage rise prevents stress on components and reduces electromagnetic interference (EMI).
