Specifications: The APH3223EH is a high-current, 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 1.2A 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 higher-power AC load switching in modern, automated SMT assembly lines. Applications include solid-state relays for major appliances (ovens, dryers), industrial motor control and soft starters, power management in server PSUs and UPS systems, and as a main AC switch in compact industrial equipment and power strips, combining high-power capability with the manufacturing advantages of surface-mount technology.
