BC547- AP TransistorBc

The BC547 is an NPN bipolar-junction triode (BJT) which means that the emitter and collector consist of an n-type substrate while the base consists of a p-type substrate. The two p-n junctions formed between these regions give rise to the various input-output characteristics of the transistors.

As the name itself indicates, a transistor basically works by transferring resistance. In other words, small current input at the base terminal leads to larger currents through the collector and emitter terminals.

The Bc547 junction transistor is mainly used for switching and amplification purposes. These two uses are briefly described below:
