TransistorThree doped regions
Emitter, Base and Collector
Base region is much thinner as compared to the collector and emitter
npn and pnp
Emitter is heavily doped, Base is lightly and collector is intermediate
Collector regions is physically largest

There are therefore two kinds of BJT, the NPN and PNP varieties.
The three layers of the sandwich are conventionally called the Collector, Base, and Emitter. Modern Transistors NPN Bipolar Junction TransistorOne N-P (Base Collector) diode one P-N (Base Emitter) diode ...
