– The BJT is constructed with three doped semiconductor regions separated by two pn junctions.
– The three regions are called emitter, base, and collector.
– There are two types of BJTs, either pnp (two p regions separated by one n region) and npn (two n regions separated by one p region).
– The C, B, and E symbols represent the common, emitter, and base regions, respectively.
– The base region is lightly doped and very thin compared to the heavily doped emitter and moderately doped collector regions.
