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 ...

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 ...

One of the semiconductor devices built in almost all electronic devices such as televisions, mobile phones, and PCs is "A transistor"is. Although I have heard of the name, actually it is not generally ...

This video explains how transistors work as switches and amplifiers in electronic circuits. Transistors control the flow of ...

Zetex Semiconductors has introduced a series of miniature NPN and PNP transistors for MOSFET gate driving in latest generation power supplies. ZXTN and ZXTP transistors The first bipolars to be ...

[Dr. Cockroach]’s goal was to build a four-bit computer out of recycled and repurposed junk. The resulting computer, called IO, consists of a single 555, around 230 PNP and NPN transistors, 230 diodes ...

An international team of scientists have created a tiny transistor that could one day help quantum computers process impossibly large amounts of information. The researchers are the first to make a ...
