What is Diode?

Full name of the diode is Semi Conductor Diode Valve. Diode is a unidirectional device that has two ends, one end of which is called an anode, and the other end is called a cathode. It works to convert AC into DC. It can also be said that in this the current flows only in one direction and not in the other direction. Because DC flows in only one direction.

Type of Diode

Reverse Bias

Reverse Bias is a special condition in semiconductor devices. A semiconductor diode is a P-N junction diode. One part of it is made of P-type semiconductor material and the other half is made of N-type semiconductor material. A diode is made by diffusing both P and N semiconductors through a special process. The semiconductor diode is used in two ways in the circuit,

What is Reverse Bias Meaning?

If any external electrical energy source like a battery is connected to a P-N Junction Diode in such a way that the (+ve) positive terminal of the battery gets connected to the N-region and the P-region gets connected to the (-ve) negative terminal of the battery, then such Biasing is called Reverse Bias. As shown in the circuit diagram below....

Working Of Reverse Bias

When the diode is connected in reverse bias, then in this condition, due to the negative end of the battery being connected to P type material, all the holes will collect at the negative end of the battery and the positive end of the battery will be N. Due to being connected to the type material, all the electrons will collect at the positive end of the battery. In this way, both holes and electrons move away from the junction and increase the thickness of the junction barrier. As a result no current flows across the junction....

What is PN Junction Diode?

Connection of p-type and n type semiconductors using a special technique results in the development of PN Junction at that point where the two types of semiconductor connect with each other. However, the nature of a device developed after junction is similar to that of diode valve. Therefore, this is termed as P-N Junction Diode....
