AQV252G3SZ is a high-capacity PhotoMOS solid-state relay designed for AC/DC dual-use switching applications. It features a miniature SOP6-pin package with a continuous load current of 3.3A and a load voltage rating of 60V peak AC/DC. The relay offers low on-resistance of 0.06O maximum, LED forward current up to 50mA, and operates over an ambient temperature range of -40°C to +85°C. With an I/O isolation voltage of 500V and total power dissipation of 450mW, it provides reliable optical isolation for sensitive circuits. Common applications include security equipment, fire-preventing systems, industrial machines, and HVAC thermostats, making it an ideal replacement for mercury and mechanical relays.
