The AQV212SX is a miniature SOP6-pin PhotoMOS relay designed for AC/DC dual-use applications, featuring a compact form factor of 4.4 × 6.3 × 2.1 mm. This device controls low-level analog signals with a load voltage rating of 60V (peak AC) and a continuous load current of 500mA, making it suitable for a wide range of industrial and consumer applications. The relay exhibits excellent electrical characteristics including a maximum off-state leakage current of 1 µA, an on-resistance of 0.83 O (typical), and a turn-on time of 0.65 ms (typical). With an I/O isolation voltage of 1,500 Vrms and operating temperature range of -40°C to +85°C, the AQV212SX provides reliable isolation and performance in telephones, measuring instruments, computers, and industrial robots.
