What is diode and type of diode

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

Current always flows the cathode even more from anode, but never vice versa. There are many utilities of these diodes about which today we will learn the definition of this article diode. Therefore, today I thought why you should be given full information about Diode and its types, so that you will be able to understand this electronic device better. So let's start without delay and know what is the diode in the right.

What is diode

It is an electronic component that allows the current to flow in just one direction. Diode consists of two types of electrodes, anode and cathode. The electrode cathode on the side of the silver color in the diode, and the angle of the triangle in the diode is the anode on the other side.

Do you know what diode works? Diode is small in appearance but its function is very large. We are used as Rectifiers, Signal Limiters, Voltage Regulators, Signal Modulators, Signal Mixers etc. When the cathode of the diode connects the terminal to the negative voltage and anode with the positive voltage then the current flows and it is called forward binding.

How diodes work

These diodes operate then when a single voltage signal is applied, across its terminals. To operate the circuit, when the DC voltage is applied, this process is called 'biasing'. Like I have already mentioned that this diode resemble one way switch by which it is either in the state of conduction or in state of non-conduction.

The 'ON' state in the diode is achieved by 'Forward biasing' which means that positive or higher potential is applied, anode can be applied negative or lower potential and cathode in a diode. If you understand it in another language, then the 'ON' state of Diode is present in the direction corresponding to the applied current, arrow head.

'OFF' state in diode is achieved by 'reverse biasing' which means that positive or higher potential is applied, cathode is applied to negative or lower potential and anode in a diode. If you understand it in another language, then in the 'OFF' state of diode, the applied current is restored in the opposite direction of the arrowhead.

In this 'ON' state, the practical diode has to face a resistance, which is called 'forward resistance'. This diode requires a forward bias voltage to switch it to the 'ON' condition, this voltage is called Cut-in-voltage.

Diode reverse behaves in biased mode when the reverse bias voltage over limits its limit, the same voltage is called the breakdown voltage. This diode is in 'OFF' state, when no voltage is applied across it.

A simple p-n juction diode is fabricate just by doping p and n type layers in a silicon or germanium wafer.

Now you may be wondering why why silicon and germanium materials are preferred for fabrication, then the answer is:

These materials are available in high purity.

In this there can be a slightly doping like one atom per ten million atoms, due to being in a desired impurity, this can change conductivity in a considerable level.

Properties of these materials change when heat and light are applied and therefore it is important to develop heat and light sensetive devices.

Types of diodes

Diode of All Types: There are many types of diodes, such as Zener diode, tunnel diode, semiconductor diode, power diode, etc. Here you will find all the information and what is used for it.
 

1. Zener Diode

It was invented in 1934 by Clarence Zener. It allows the current to move in the same direction as a normal diode, but when the voltage breakdown voltage becomes more than the voltage, it also allows the current to move in the opposite direction. This invention was done to avoid the incoming voltage immediately. This diode works like a voltage regulator.

2. Constant Current Diodes

The main work voltage of this diode is to keep regular on the current. This current is also called diode or diode connect transistor.

3. Shockley Diode

This was the semiconductor diode with the first Pnpn layer. It was invented by William Shockley in the 1950s and this diode was named after him.

4. Light Emitting Diode (LED)

It turns diode electronic energy into light energy. It is also called light-emitting diode. It was invented in 1968. This diode works on the status of forward bios. Earlier this diode was used in Indoor Lamps but now it is being used at a large scale. It is now being used in traffic signal cameras too.

5. Schottky Diode

This diode is composed of semiconductor material and metal junction. It has low drop in voltage. Due to being a metal in it, this diode has the ability to perform a lot of current flux. The name of this diode was named after German physicist Walter H. Schottky.

6. Tunnel Diode

This diode is used to switch very fast. It is used where nanos are to be done in seconds. It was invented in 1957 by Leo Esaki, so it is also called Esaki Diode.

7. Varactor Diode

It works like variable capacitors. It is used in many devices such as cell phones, satellites, pre-filters etc.

8. Laser Diode

It is also known as LD or injection laser diode. It works just like the Light Emitting Diode. But it creates a laser beam instead of the light. It is used today in fiber optic, barcode readers, laser pointers, CD / DVD etc.

What is diode work

Let's get more information about the uses of diode.

Rectification - Rectification in this means converting AC voltage to DC voltage. The common rectification circuits that are used more often are half wave rectifier (HWR), full wave rectifier (FWR) and bridge rectifier.

Half wave rectifier: These circuit rectify either positive or negative pulse to input AC.


Bridge rectifier: This circuit converts the entire AC signal i into DC.

Clipper - Diode used can also be used to clip off some part of a pulse, without any distortion created in the other parts of the waveform.

Clamper - A clamping circuit limits the voltage levels to exceed a limit, for which they have to shift to DC level. No one will affect the peak to peak in this clamping. In these clamping circuits, diodes are used in which the resistors and capacitors are used. Sometimes independent DC sources are used to provide any additional shift.

  • It is used to convert Alternate Current to Direct Current.
  • Diode is also used in Radio Demodulation.
  • It is used to turn the current in the circuit.
  • It is used in Voltage Regulator and Signal Mixing.

Conclusion

I hope that you have a choice of what my diode is. This is my usual effort that readers should be given full information about the type of diode, so that they do not need to find any other sites or internet in the context of that article.

Thanks you....
