Bjt as a switch simulation

WebAug 2, 2024 · The first bipolar junction transistor was invented in 1947 at Bell laboratories. “Two polarities” is abbreviated as bipolar, hence the name Bipolar junction transistor.BJT is a three terminal device with Collector (C), Base (B) and Emitter (E). Identifying the terminals of a transistor requires the pin diagram of a particular BJT part, … 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.
