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 that share a thin n-doped region. N-type means doped … See more 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 … 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 … 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. The junction version known as the bipolar junction transistor (BJT), invented by … 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 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. Because electrons carry a negative charge, … 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
WebAs NPN transistor consists of the emitter of N-type, the majority charge carriers in NPN transistor are electrons. These electrons when move from low resistance junction, i.e. emitter-base junction to the junction which consists of high resistance region, i.e. collector-base junction, it generates current. WebAs said earlier, we will operate our NPN transistors in the saturation region. This means that the collector current will not be dependent on the base current anymore - it reaches a maximum set only by the collector resistance. I will use 5V in most of my circuits but we will vary that around. I did not measure the forward voltage of the LEDs ...
