The AQY212GS is a high-capacity, 1 Form A PhotoMOS relay designed for AC/DC dual-use switching applications. It handles a peak AC load voltage of 60V and a continuous load current of 1.0A, with a peak current capability of 3A. This solid-state relay features a maximum on-resistance of 0.7 Ω and provides an I/O isolation voltage of 1,500 Vrms. Housed in a miniature SOP4-pin package, it is well-suited for applications such as measuring instruments, testers, and I/O for security and disaster-preventing systems.
