The AQV210S is a miniature PhotoMOS relay designed for low-level analog signal control in AC/DC dual-use applications. It features a compact SOP6-pin package with dimensions of 4.4 × 6.3 × 2.1 mm, providing space-efficient integration for modern electronics. The device operates with a load voltage of 350V (peak AC) and supports a continuous load current of 120mA in A-connection mode, with maximum on-resistance of 30O at 5mA LED current. Key electrical characteristics include a low off-state leakage current of maximum 1µA, turn-on time of 0.25ms, and turn-off time of 0.04ms, along with an I/O isolation voltage of 1,500Vrms. The AQV210S operates reliably across an ambient temperature range of -40°C to +85°C and is ideal for applications in telephones, measuring instruments, computers, and industrial robots where compact, high-voltage switching with minimal leakage is required.
