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 ...

Such are the breadth of functions delivered by integrated circuits, it’s now rare to see a simple small-signal transistor ...

The transistor is probably the most important invention in electronic engineering and the basis for nearly all integrated circuits (ICs). The transistor is a three-terminal electronic device that can ...

The two types of standard transistors are PNP and NPN which differs in circuit symbols. The layers of semiconductor material used to make the transistor are denoted by the letters. To keep a straight ...

The 2SA1010 is a PNP silicon epitaxial transistor for high-voltage, high-speed switching that features low collector saturation voltage. It has fast switching speed with 2CS2334 as a complementary ...

Transistors are tiny switches that can be triggered by electric signals. They are the basic building blocks of microchips, and roughly define the difference between electric and electronic devices.

Matching a sensor interface with a programmable logic converter or controller hardware that can accept only one type of input—npn or pnp—can be difficult. The last-stage modification circuit described ...

They had no way of knowing all that the transistor could do, but the administrators at Bell Labs still knew they were on to something big. They were about to hold a huge press conference to announce ...
