Specifications: The APH1213E 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 600mA 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: A reliable relay for medium-power AC switching. Common applications include industrial control of actuators, contactors, and small three-phase motor components, HVAC compressor and heater relays, power supply inrush current control, and as an isolated interface for microcontrollers to safely switch AC line voltage in industrial automation, test equipment, and appliance control boards.
