Specifications: The APY212GH is a high-current, high-isolation relay in a DIP-4 through-hole package. It is rated for 1.8A at 60V (AC/DC) with a 70mΩ on-state resistance and is fortified with 5000Vrms of isolation. Switching times are 1.5ms for turn-on and 50μs for turn-off. It is designed for operation in challenging environments, functioning from -40°C to 85°C with a precise 1.32-1.46VDC control signal.

Application Scenarios: This relay is suited for applications demanding both substantial current and maximum safety isolation. It is employed in isolated gate driver power supplies for IGBTs/MOSFETs, as an output switch in medical-grade battery chargers, for controlling high-power actuators in industrial machinery, and in test equipment designed for hazardous locations, where its robust isolation is as critical as its current handling capability.
