WebApr 9, 2024 · BJT definition and characteristics. BJT transistor is a three terminal semiconductor device, based on three layers of p and n layers, with different doping concentration. BJT transistor can be two types – pnp and npn BJT transistor. Bipolar junction transistor (BJT) is characterised by three regions – base (B), collector (C) and … WebThe BJT is "cutoff" because IC is essentially zero and all of VCC appears across the transistor collector-emitter terminals. The BJT is "saturated" if IC reaches its maximum value along the load line (IB > 100 μA). Therefore, the transistor can be operated as an OFF switch with IB = 0 μA and as an ON switch with IB = 100 μA.
