A bipolar junction transistor (BJT) is a type of transistor that uses both electrons and electron holes as charge carriers. In contrast, a unipolar transistor, such as a field-effect transistor, uses only one kind of charge carrier. A bipolar transistor allows a small current injected at one of its terminals to control a much … See more By convention, the direction of current on diagrams is shown as the direction that a positive charge would move. This is called conventional current. However, current in metal conductors is generally due to the flow of electrons. … See more Bipolar transistors have four distinct regions of operation, defined by BJT junction biases. Forward-active (or … See more The bipolar point-contact transistor was invented in December 1947 at the Bell Telephone Laboratories by John Bardeen and Walter Brattain under the direction of William Shockley. … See more The BJT remains a device that excels in some applications, such as discrete circuit design, due to the very wide selection of BJT types available, … See more BJTs exist as PNP and NPN types, based on the doping types of the three main terminal regions. An NPN transistor comprises two semiconductor junctions that share a thin p … See more BJTs consists of three differently doped semiconductor regions: the emitter region, the base region and the collector region. These regions are, respectively, p type, n type and p type in a PNP transistor, and n type, p type and n type in an NPN transistor.

WebJul 10, 2024 · A BJT acts like an open switch when it operates in the cutoff region. In figure 7, you can see that the npn BJT is operating in the cutoff region since the voltage at the base terminal is 0V. Therefore, the base-emitter junction is not forward-biased and if we will not consider the leakage current, all of the currents, I B and I C are zero. hugh thompson biographyWebBipolar Junction Transistors, or BJTs, offer higher trans-conductance than MOSFETS and don't require separate gate drivers. A particular strength is that they are current amplifiers capable of very high current densities.
