V CE is small, e.g. 50-100 mV, but quite large collector and base currents (I C & I B) can ow. This region is not used for ampli cation. There is a low resistance between the C and E terminals; the BJT acts like a closed switch. Figure 4 shows an actual circuit of a BJT

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.
