BC337 is an NPN transistor mainly used for lower power audio amplification and switching purposes.
It contains three terminals known as emitter, base, and collector.
The small current chance at the base side is used to produce large
current change at the remaining terminals. This phenomenon is used for
amplification purposes.
BC337 comes with three layers i.e. one p-doped layer and two
n-doped layers. The p-doped layer is sandwiched between two n-doped
layers. The base terminal is positive and the remaining two terminals
are negative.
