Specifications: The APV256AEH is the surface-mount SMD-6 version of a medium-voltage PhotoMOS SSR. It is a 1 Form A (SPST-NO) relay rated for 200mA at 600V AC/DC. It has a 13Ω on-state resistance, provides 3750Vrms isolation, and switches with 700μs (on) and 70μs (off) times. It operates from -40°C to 85℃ with a 1.1-1.7VDC control input. Application Scenarios: Suited for the same medium-current, high-voltage switching as the DIP version but in a compact SMD package. Ideal for modern designs in industrial motor drives, power supplies, renewable energy systems, and HVAC controls, enabling automated assembly and higher component density while maintaining reliable performance at several hundred volts.
