What is a diode | How does a diode work? What type of diode is there

 What is the Diode and (Types of Diode)

What is diodes


What is the Diode

Do you know what this diode is? If you have ever been to an Electorinics shop, then you have probably seen this small semiconductor device.  But due to lack of information, you probably would not have even recognized it.By the way, for your information, let me tell you that these diodes are very simplest two-terminal unilateral semiconductor device.These diode are 'one way' sign of electrical circuits.In this, current is allowed to flow in only one direction.Each diode has a positive end, called an anode, and also a negative end called a cathode.

Current always flows from anode to cathode even more, but never upside down.There are many utilities of these Diodes about which today we will know the definition of this article diode.

So today I thought that why should you all be provided complete information about Diode and its types, which will make it easier for you to understand this electronic device better.So without delay, let's start and know what is this diode.

What is the Diode and Types of Diode

There are several types of diodes, which will be explained separately to you below, but what is usually a diode symbol is given below.

 As you all know that there are many types of diodes, so the symbols of all diodes are also different.And these symbols are used to make a circuit diagram where it is shown that it is a diode and what its value is.. And in the photo above, you can see that the diode is cylindrical and has a white strip on one side, which means that it is the terminal or the terminal cathode on this side.

What are the types of diodes

What is diodes | diodes working, types and uses


The diodes are placed in different categories according to their working. Diodes are of 9 types.All diodes have different work and almost all diodes have different work from each other.Some diodes give light on supply and some diodes give light on supply, so there are different types of diodes, which are given below and the symbols are also given.

  1. Zener Diode
  2. Light Emitting Diode (LED)
  3. Constant Current Diodes
  4. Schottky Diode
  5. Shockley Diode
  6. Photodiode
  7. Tunnel Diode
  8. Varactor Diode
  9. Laser Diode


Zener diode

Zener diode is like a normal diode.  But not everyone knows that Zener Diode Kya Hai.We tell you that the live diode allows the current to go to one side like a normal diode, but when the voltage exceeds the Breakdown Voltage, it also allows the current to go in the reverse direction. The Ginger diode was invented in 1934 by Clarence Zener.And this was done to avoid immediate voltage pulses.And this diode acts as a voltage regulator.

Light Emitting Diode (LED)

It works to convert diode electric energy into light energy. Its invention happened in 1968.This diode works to connect again with the help of light in frontward bos to make energy to electrons and holes under electroluminescence method. This saves a lot of power in which people prefer to use it in homes.

Constant Current Diodes

Constant Current Diode is known by many names, among which Current Regulating Diode, Current Limiting Diode, Diode Connected Transistor is the main one.  The function of this diode is to regulate the voltage at a certain current.

tunnel diode 

The tunnel diode is also called Esaki Diode because it was invented in 1927 by the Japanese Nobel Prize winner Leo Esaki.  This diode is used to switch very fast.  Whenever a work has to be done in nano seconds, the tunnel diode is used.

Laser diode

Laser diode injection is also popularly known as laser diode. This diode acts like a Light Emitting Diode but instead of the light used in it, it creates a laser beam. Laser diodes are used these days for barcode readers, laser pointers and fibers.  Apart from optic, many other functions are also done.

What is a diode, how does it work, what is its working, and you have got information about the type of diode and its uses.

Thanks for reading......
