Specifications: The APH0213EH 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 in compact, automated assemblies. Applications include smart home appliance control boards, power management in IoT gateways, industrial sensor and actuator interfaces requiring AC power, compact power supplies, and energy metering systems, providing a high-voltage AC switch in a miniature SMD package suitable for high-volume manufacturing.
