The AQV215SZ is a miniature SOP6-pin PhotoMOS relay designed for AC/DC dual-use applications with a 100V peak load voltage rating and 300mA continuous load current capacity. This device features extremely low closed-circuit offset voltage enabling control of low-level analog signals without distortion, combined with a maximum off-state leakage current of 1 µA for reliable signal integrity. The compact SOP6 package measures 4.4 × 6.3 × 2.1 mm, providing approximately 25% of the volume and 50% of the footprint compared to traditional DIP packages. Operating over a temperature range of -40°C to +85°C with an I/O isolation voltage of 1,500 Vrms, the AQV215SZ is well-suited for applications in telephones, measuring instruments, computers, and industrial robots where space constraints and signal fidelity are critical requirements.
