Specifications: The APH3223E is a high-current, high-voltage AC-output PhotoMOS SSR in a DIP-7 through-hole 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 robust, higher-power AC load control. Typical applications include residential and commercial appliance main power control (e.g., water heaters, air handlers), industrial machine tool power switching, stage lighting control, power distribution in control panels, and as a reliable solid-state alternative to electromechanical contactors in various 1-phase AC applications, offering long life and silent operation.
