NPN transistor
Bipolar
junction transistors are of two types mainly. NPN transistor is one of the types of Transistors (BPT). NPN
stands for Negative-Positive-Negative configuration. It is the most often used
in all types of
transistors. Basically, in NPN transistors two n-type (negative)
materials dope the single p-type (negative) materials.
In
simple words, one p-type semiconductor material is present between the
two n-type semiconductor materials. They are the most used type of bipolar
junction transistors and the reason behind this is the mobility of their
electrons are many times higher than that of the holes (mobility of holes).
