PDB-C157F

A photodiode is a type of semiconductor device which converts light into an electrical current. It is typically composed of a semiconductor material such as silicon or germanium, and has a potential difference between the junction of two layers. When light is incident upon the photodiode, it produces an electric current proportional to the intensity of the incident light. Photodiodes are used in a variety of applications, including light detection, radiation monitoring, and optical communications.

PDB-C157F is a general-purpose photodiode which can be used for a wide range of applications.
