How Photodiode 5mm Works
Photodiodes operate on the principle of the photoelectric effect, where light energy is absorbed by the semiconductor material and converted into electrical charge. The 5mm size refers to the diameter of the photodiode, which is a standard size for many applications. When light strikes the photodiode, the electrons in the semiconductor material are excited and move towards the external circuit, generating an electrical current. This current is proportional to the intensity of the incident light.
