Specifications: The APH0223E is a 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 300mA 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: Suited for lower-current AC switching in high-voltage environments. Applications include control and monitoring circuits in power supplies, status indicator switching in high-voltage equipment, auxiliary power control in industrial systems, interfacing low-voltage logic with AC mains for signaling or control in appliances, and as a reliable component in energy management and smart metering systems.
