Specifications: The APV256BEH is the surface-mount SMD-6 version of a medium-voltage, medium-current PhotoMOS SSR. It is a 1 Form A (SPST-NO) device rated for 400mA at 600V AC/DC. It has a 4Ω on-state resistance, provides 5000Vrms isolation, and switches with 700μs (turn-on) and 70μs (turn-off) times. It operates from -40°C to 85℃ with a 1.1-1.7VDC control input. Application Scenarios: Suited for the same applications as its DIP counterpart but in a compact SMD package for automated assembly. Ideal for modern designs requiring robust isolation at several hundred volts, such as industrial motor drive interfaces, power supply control, renewable energy system monitoring, and compact HVAC controls, enabling higher board density and manufacturing efficiency.
