NPN and PNP are two types of transistors. Transistors are semiconductor devices made of doped p-type and n-type junctions. This article mainly introduces the differences between this two kinds of transistors, the methods of distinguishing them, and the application of them. ...
The other places we use transistors are sensors, amplifiers, oscillators, detectors, modulators, and various electric circuits to perform functions. Summary So, we understood that both PNP and NPN transistors are current controlling devices where conduction is carried out by charge carriers viz: holes...
How do npn and pnp transistors operate?Fig. 1: Operation of the npn transistor A bipolar transistor (bipolar junction transistor: BJT) consists of the collector, base, and emitter regions, with the very thin base region located between the collector and emitter re...
How to choose between the NPN and PNP transistors The two transistors can be used to perform the same thing, such as switching, but how to use them differs. Below I explain how both the NPN and PNP function and then depending on your application, you can choose whichever transistor is mor...
The main difference between NPN and PNP transistors includes what are PNP and NPN transistors, construction, working, and their applications. What is a PNP Transistor? The term ‘PNP’ stands for positive, negative, positive, and also known as sourcing. The PNP transistor is a BJT; in this ...

Another concept differentiating NPN and PNP transistors is that since voltage is allocated differently, they have opposite current flows at the output. In an NPN transistor, output current flows from the collector to the emitter. In a PNP transistor, output current flows from the emitter to the ...

The emitter electrode of the NPN transistor is connected with the collector electrode of the PNP transistor. The symmetrical transistor can be directly used for making a circuit board of an energy-saving lamp, and there is no need of welding the two transistors at corresponding positions, thereby...
PNP base high voltage. Thepole electrode and emitter are open, that is, they do not work. If the base isplus a low potential, the collector is short circuited with the emitter. Transistors: the mostcommonly used are triode and diode two. The transistor is represented by thesymbol BG (old...
