A diode is a two-terminal digital part that conducts electrical present in just one route. Diodes are utilized in all kinds of digital purposes, resembling rectifying AC present, defending circuits from overvoltage, and producing mild. There are a lot of various kinds of diodes, every with its personal distinctive traits and purposes.
The commonest sort of diode is the p-n junction diode. P-n junction diodes are produced from a semiconductor materials, resembling silicon or germanium. The semiconductor materials is doped with impurities to create a area of constructive cost (the p-region) and a area of damaging cost (the n-region). When a voltage is utilized to the diode, present will stream from the p-region to the n-region. Nevertheless, present won’t stream in the wrong way.
