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.

Typically, a transistor – which is based on the transport of electrons in a solid (i.e., a solid-state device) and not in a vacuum, as in the vacuum tubes of old – consists of at least three terminals ...

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 ...
