A diode is one of the electronic components, and its biggest characteristic is unidirectional conductivity, which means that current can only flow in one direction through the diode. The functions of a diode include rectification circuits, detection circuits, voltage stabilization circuits, and various modulation circuits, all of which are mainly composed of diodes. The working principle of a diode is that a crystal diode is a p-n junction formed by a p-type semiconductor and an n-type semiconductor. Space charge layers are formed on both sides of the interface, and a self built electric field is established. When there is no external voltage, the diffusion current caused by the difference in carrier concentration on both sides of the p-n junction is equal to the drift current caused by the self built electric field, and it is in an electric state
