What is The Difference Between PNP and NPN transistor?

The Major Difference Between PNP And NPN Transistor is that in PNP transistor, positive voltage is given to the emitter terminal and current flows from emitter to the collector and sufficient negative current flow from the base while in NPN Transistor positive voltage is given to the collector terminal, current flows from collector to emitter.

Which type of transistor is most commonly used?

Transistors are made of crystals of semiconductor materials like silicon or germanium. Because the conduction between these materials is high compared to those conductors like copper silver and non-conductors like wood. Semi-conductor can be imparted peculiar electrical properties by adding some impurities in the semi-conductors.


In this procedure, electrons can be added to the semiconductors to start a current or electrons can be removed to cause the holes in the semi-conductors.

When electrons are added by mixing an impurity to constitute a current, an N-type semiconductor is produced.

When electrons are removed from semiconductors, a p-type semiconductor is produced.

A certain combination of N-Type and P-type semiconductors give transistors the rectifying or amplifying properties of valves. They are made up of three layers, N-P-N ( ap sand witched between two N-type) or P-N-P ( an N sand witched between two P types).

Electronic is based on integrated circuits which are made up of four various types of semiconductors. The transistor is simply a two-way reverse link, i.e, a  two-way diode but the difference between PNP and NPN  is a mechanism of formation of both.

Transistor Type NPN needs a voltage or a positive signal on the base of the base to work. The Transistor type PNP it will not work unless a negative effort on the edge of the base.

Difference between PNP and NPN Transistor:

The presence of opposite poles as in magnets (north and south), electricity (negative and positive). And the uneven distribution of shipments on two atoms connected to a chemical compass.

NPN Transistor

Transistor manages the electrons of the impulse which is E to the collector which is C.

PNP Transistor

Transistor manages the electrons of the complex which is C to the impulse which is E.

This is how the NPN works!

You can increase the voltage on the NPN base. The transistor is run more and more efficiently until the charge is fully charged

Drive to the pool….!

If the voltage is reduced to the base of the NPN transistor, the transistor will switch to a voltage lower and lower and thus will not manage the shipments from the drive to the pool is extinguished.

In short, the NPN transistor works opposite PNP. I hope that I have been successful in explaining the transistors and their work.
