Specifications: The APH1213EH is a high-voltage AC-output PhotoMOS solid-state relay in a surface-mount SMD-7 package. It is a single-channel, 1 Form A (SPST-NO) device capable of switching 600mA at up to 600V AC. It provides robust 5000Vrms isolation and features a fast 100μs turn-on time. Designed for reliable operation, it works within a temperature range of -30°C to 85℃ and is controlled by a precise 1.21-1.3VDC input. (Note: On-state resistance and turn-off time specifications are not provided in the source data). Application Scenarios: This relay is suited for modern, automated manufacturing of medium-power AC load control systems. Typical applications include solid-state relays in appliance control boards (for motors, heaters), industrial contactor driver modules, power management in HVAC systems, and as a main AC switch in compact power supplies and industrial controllers, enabling high component density and efficient assembly.
