A diode is a two-terminal digital element that conducts electrical present in just one route. Diodes are utilized in all kinds of digital purposes, comparable to 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 kind of diode is the p-n junction diode. P-n junction diodes are comprised of a semiconductor materials, comparable to silicon or germanium. The semiconductor materials is doped with impurities to create a area of constructive cost (the p-region) and a area of destructive cost (the n-region). When a voltage is utilized to the diode, present will stream from the p-region to the n-region. Nonetheless, present is not going to stream in the wrong way.
