Specifications: The APH0223EH 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 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 applications where space-saving SMT assembly is required. Applications include compact power supplies, smart meters, IoT device power control, appliance control boards, and industrial sensor interfaces requiring AC power switching, providing a high-voltage switch in a miniature package suitable for automated high-volume manufacturing.
