In this article we will discus
what is diode
Types of diode
Application of diode.
In today’s article we are going to tell about a component of electronics Which is called diode.

what is diode
Diode is a device that allows current to flow one side
It has two legs One is cathod and one is called anode Cathode side is usually of silver color As shown in the picture
Symbol of diode
[otw_is sidebar=otw-sidebar-3]
The diode’s symbol is shown in the picture In that there is a plus symbol on the anode side And the negative side has been shown to –
Every diode has only one symbol and it has two legs The circuit shows the diode’s circuit symbol. Typically the diode works in Forward bias The diode has a anode side in the symbol
Battery’s positive terminal will come on the anode side If you apply negative here, there will be no current flow
Working of diode
A diode is used in two conditions A Forward bias and the Second reverse bias
1 forward bias
In the picture we have used the diode to be forward bias
In which the positive terminal of the battery is placed on the anode site of the diode And put a resistance on the cathode side of the diode And as soon as we connect to the battery, the diode forward bias will work
And will be current Flow
2 reverse bias
In reverse bias we have changed the diode directions We have placed negative side on the diode’s positive terminal. This will not cause current flow of the battery, the diode will work in reverse bias
As illustrated in the picture as clear.

Types of diode
There are too many types of diodes From which we have given the names of some diodes below
1 laser diode
3 tunnel diode
4 photo diode
5 schottky diode
6 gunn diode
7 pin diode
8 light Emitting diode
9 Backward diode

The diodes that occur are PN junctions.
A zener diode can be used to provide the stabilized output voltage despite of the variation in the input voltage. As the voltage above or equal to the Zener breakdown of the Zener Diode is applied across the Zener Diode in the reverse direction the Zener Breakdown of the diode occurs and output of the Zener diode becomes equal to what Zener Diode is designed to provide
In today’s post we will study what is this diode and types of diode and its uses and application There are too many types of diodes
