A field-effect transistor (FET) is a type of transistor that uses an electric field to control the current flow through a semiconductor channel. FETs are widely used in electronic circuits due to their high input impedance, low output impedance and high gain.

WebAug 2, 2024 · 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, it will be available in the datasheet. There are two types of BJT - NPN and PNP transistors. In this tutorial we will talk about the NPN transistors. 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.
