Specifications: The APH2223EH is a high-voltage AC-output PhotoMOS SSR in a surface-mount SMD-7 package. It is a 1 Form A (SPST-NO) relay capable of switching 900mA at up to 600V AC. It provides 5000Vrms of isolation and features a fast 100μs turn-on time. It operates from -30°C to 85℃ and is controlled by a precise 1.21-1.3VDC input. (Note: On-state resistance and turn-off time are not specified in the provided data). Application Scenarios: Designed for medium-power AC load switching in compact, modern designs. Applications include solid-state relays for appliance control (e.g., dishwasher heaters, oven elements), industrial contactor and motor starter control circuits, power management in HVAC units, and as a reliable AC switch in automated industrial equipment and power supplies, leveraging the benefits of surface-mount technology for automated assembly and space savings.
