Also called a "bipolar junction transistor" (BJT), it is one of two major transistor categories; the other is "field-effect transistor" (FET).

Field-effective transistors (FETs) are a popular choice in the mid-power range (30 W to 1 KW) because FET conduction losses are generally lower than BJT conduction losses. However, in low-power ...

“The Bipolar Junction Transistor (BJT, such as NPN and PNP) was invented by Bell Labs in 1947.” Not exactly. The transistor demonstrated by Bell Labs in ’47 was a point contact transistor.

Transistors are tiny switches that can be triggered by electric signals. ... A BJT is made from three alternating layers of silicon types, thus has either a “PNP” or “NPN” configuration.

Duration: 5 hours. In this module on BJTs (bipolar junction transistors), we will cover the following topics: BJT Device structures, Energy band diagrams, Active bias, Leakage current, Recombination ...

Conversely, the power bipolar junction transistor (BJT) is generally considered an outdated device that has poor switching performance and is unfamiliar to today’s power system engineers. Recently, ...

“Indium oxide contains oxygen-vacancy defects, which facilitate carrier scattering and thus lower device stability,” says ...
