The FODM8801AR2 is an optocoupler manufactured by ON Semiconductor, in a surface mount design. It contains one channel and has an output type of transistor. It has a dielectric strength rating of 3.75 kilovolts (kV). It features a narrowbody package which is designed to fit into cramped spaces, and is used to detect differences in voltage levels between two circuits without allowing any current to flow between them. This device is ideal for use in applications such as logic level translation, noise avoidance, and isolation of digital signals.
