Manufacturing companies, particularly those that mass-produce electronic circuits, work pretty much around bipolar junction transistors, like PNP and NPN. However, choosing between these two BJTs can ...

A transistor is a key component in electronics, often used as a switch or to amplify a signal from a sensor. NPN (negative-positive-negative) transistors are the most used transistor. An illustration ...

A Planet Analog article, “ 2N3904: Why use a 60-year-old transistor? ” by Bill Schweber, inspired some interest in this old ...

In the early days, PNP bipolar transistors were common, but the bulk of circuits you see today use NPN transistors. As [Aaron Danner] points out, many people think PNP transistors are “backward” but ...

When we were in school, every description of how transistors work was pretty dry and had a lot of math involved. We suppose you might have had a great instructor who was able to explain things more ...

What is a Programmable Unijunction Transistor (PUT)? Simple – it is a three-lead electronic semiconductor device, similar to a unijunction transistor (UJT), except that its behaviour can be controlled ...

Swedish researchers claim to have developed a new type of transistor that is 50 times more energy efficient than today’s devices. It is also said to be the first to be developed using nanotechnology.
