Working Principle of Photodiode 3mm

A photodiode 3mm is a semiconductor device that utilizes the photoelectric effect to convert light into an electrical current. When light with sufficient energy falls on the photodiode, it generates electron-hole pairs in the depletion region of the junction. These electron-hole pairs contribute to the flow of current through the device. The photodiode operates in reverse bias, which enhances the separation of electron-hole pairs and increases the photoelectric conversion efficiency.

The 3mm photodiode typically consists of a p-n junction, where the p-type material is doped with acceptor impurities, and the n-type material is doped with donor impurities. When light is incident on the photodiode, the electron-hole pairs are generated in the depletion region. The electric field across the junction separates the electrons and holes, creating a flow of current that can be measured and utilized.
