Working Principle

Photodiodes are composed of a semiconductor material such as silicon, which has been doped with atoms to create a p-n junction. When the p-n junction is exposed to light, electrons and holes are created in it. The electrons move to the n-side, creating a current, while the holes move to the p-side, thereby increasing the voltage. The electron-hole pairs created can then be used to create an electric current.

The SD012-UVA-011 is a supremely sensitive photodiode, designed to be used in ultra-violet light applications. It features a 20µm diameter active area which captures all the incoming light for better reception. Due to its small size and high sensitivity, it is very efficient and cost-effective for many applications.
