There are numerous differences between NPN and PNP transistors, and even though both are bipolar junction transistors, the direction of current flow is the name of the game.

An NPN transistor has three legs. In circuit diagrams or symbols, the legs of an NPN transistor can be identified as follows: Base (B) : Usually located in the middle.

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 “backwa… ...

The damn thing worked – it showed the schematic symbol for an NPN transistor with Collector, Base, and Emitter connected to Pins 1,2,and 3 respectively. Flipping the pins around and re-testing ...

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

A new material can withstand 'billions' of electrical cycles without wearing out — and scientists say it could transform ...

The first transistor was about half an inch high. That's mammoth by today's standards, when 7 million transistors can fit on a single computer chip. It was nevertheless an amazing piece of ...

The transistor is the most evolved piece of technology in history, contends Will Swope, a vice president at Intel. “Before, we were making them one at a time. Now we’re making them a billion ...

On April 14, 1954, Gordon Teal showed TI's Vice President, Pat Haggerty, a working silicon transistor. Haggerty knew if they could be the first to sell these new transistors, they'd have it made.
