AQV255G3A is a PhotoMOS HE 1 Form A high capacity solid state relay designed for AC/DC dual use applications requiring reliable load current control. It features a maximum load voltage of 100V (peak AC) and a continuous load current of 2.4A at A connection, with on-resistance of 0.07O typical (0.12O max) and I/O isolation voltage of 1,500 Vrms. The device operates over an ambient temperature range of -40°C to +85°C and comes in a surface-mount DIP6-pin package. With low LED operate current (0.5mA typical, 3mA max) and fast switching times (turn on time 1.8ms max, turn off time 0.5ms max), this relay is ideal for security equipment, fire-preventing systems, industrial machines, and HVAC temperature controllers where compact size and high reliability are essential.
