Specifications: The APH1223EH 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 600mA 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: Suitable for medium-power AC load switching where automated SMT assembly is required. Applications include solid-state relays for appliance control (e.g., washing machine heaters), industrial AC motor starters and contactor controls, power management in HVAC systems, and as a reliable AC switch in compact power supplies and industrial control modules, offering the benefits of surface-mount technology in high-voltage applications.
