diodealso called crystaldiode, abbreviationdiode. Among electronic components, a device with two electrodes allows current to flow in only one direction. Many applications use its rectifying function.

What does it do?

diodeIt is one of the most commonly used electronic components. Its biggest characteristic is that it conducts electricity in one direction, that is, the current can only flow fromdiodeflows in one direction,diodeIts functions include rectifier circuit, detector circuit, voltage stabilizing circuit, and various modulation circuits, which are mainly composed ofdiodeThe principle is very simple, precisely becausediodeThe invention of other components led to the birth of our current colorful electronic information world.

What categories does it have:

1. Classification according to structure

semiconductordiodeMainly relies on PN junction to work. The point contact type and Schottky type, which are inseparable from the PN junction, are also included in the generaldiodewithin the range. Including these two models, according to the characteristics of PN structure surface, the crystaldiodeDivided into the following types: 1. Point contact typediode2. Key typediode3. Alloy typediode4. Diffusion typediode5. Countertop typediode6. Flat typediode7. Alloy diffusion typediode8. Epitaxial typediode9. Schottkydiode

Classified by use

Quick shutdown (step recovery)diode15. Schottkydiode16. Dampingdiode17. Transient voltage suppressiondiode18. Double basediode(Single-junction transistor) 19. Luminescencediode

3. Classification according to characteristics

General point contact typediode

High reverse withstand voltage point contact typediode

High reverse resistance point contact typediode

High conductivity point contact typediode

The above is what I have concludeddiodeKnowledge point, friends, have you learned new knowledge?
