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 ...

In a world of mosfets and hemts, it is not often you see a new pnp power transistor. Earlier this year, Diodes did just that, with some 2.5W dual pnp bipolars for switching automotive lighting – ...

Transistors are everywhere—in your computer, car, phone, and refrigerator—but they’re not shrinking fast enough to satisfy our hunger for ever-faster devices. A new kind of light-based transistor ...
