Npn punch through
WebA punch-through semiconductor device having three regions of alternate conductivity types which exhibit punch-through conduction characteristics similar to the breakdown characteristics of a Zener diode when a voltage equal to the punch-through voltage magnitude is applied across the device. 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 cathode region, and the NPN like two diodes sharing a P-type anode region. Connecting two diodes with wires will not make a … Meer weergeven 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 … Meer weergeven 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-doped region, and a PNP transistor comprises two semiconductor junctions … Meer weergeven Bipolar transistors have four distinct regions of operation, defined by BJT junction biases. Forward-active (or simply active) The base–emitter junction is forward biased and the base–collector junction is reverse biased. … Meer weergeven 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 … Meer weergeven BJTs consists of three differently doped semiconductor regions: the emitter region, the base region and the collector region. These … Meer weergeven The bipolar point-contact transistor was invented in December 1947 at the Bell Telephone Laboratories by John Bardeen and Meer weergeven 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.
