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 simply active) The base–emitter … See more BJTs can be thought of as two diodes (P–N junctions) sharing a common region that minority carriers can move through. A PNP BJT will function like two diodes that share an N-type … 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 See more BJTs consists of three differently doped semiconductor regions: the emitter region, the base region and the collector region. These regions are, … See more The bipolar point-contact transistor was invented in December 1947 at the Bell Telephone Laboratories by John Bardeen and 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, and because of its high transconductance and output resistance compared to MOSFETs.

WebA simple definition of collector in BJT is that it is the part of the transistor which outputs the amplified current. As with any transistor, the core working concept of a BJT is that a small amount of current flowing between the base region and collector region causes a larger current to flow between the collector and emitter regions.
