"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. " - Bjt load switch
