Answer:

A bipolar transistor (bipolar junction transistor: BJT) consists of three semiconductor regions forming two junctions. There are two types of structure: npn and pnp. Products with npn up to 800 V and pnp up to -600 V are available. In addition, there are also bias resistor built-in transistors (BRTs).

It is a current controlled device. The three terminals of the BJT are the base, the collector and the emitter. A BJT is a type of transistor that uses both electrons and holes as charge carriers. ... A diagram of these two types of bipolar junction transistors is given below.
