Specifications: The APH0213E 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°C 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 requiring high voltage and strong isolation. Common uses include control circuits for small AC motors, solenoid valves in industrial equipment, auxiliary power switching in HVAC and appliance controls, status indicator or alarm circuit switching in power systems, and as a reliable interface for microcontrollers to control AC mains circuits in various industrial and commercial products.
