The AQW214AZ is a compact PhotoMOS relay designed for AC/DC dual-use applications with a maximum load voltage of 400V peak AC and 100mA continuous load current in single-channel operation (130mA peak). This 8-pin DIP surface mount terminal device features high sensitivity and high-speed response characteristics, with a low off-state leakage current of maximum 1 µA, making it suitable for controlling low-level analog signals. The relay operates over an ambient temperature range of -40°C to +85°C and can be configured as either two independent 1 Form A channels or a single 2 Form A relay. Typical applications include high-speed inspection machines, telephone equipment, and computer systems where reliable signal switching and isolation are required.
