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 ...

Zetex Semiconductors pair of low-voltage PNP transistors feature low saturation voltages and high currents, serving as cost-effective switchers in a variety of slim-line portable applications. Zetex ...

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 ...

PLANO, Texas--(BUSINESS WIRE)-- Diodes Incorporated (DIOD) today announces an expansion of its automotive-compliant* bipolar transistor portfolio with the introduction of the DXTN/P 78Q & 80Q series.

The first transistor was successfully demonstrated at Bell Laboratories in Murray Hill, New Jersey, in 1947. This three-terminal device has spawned many of the electronics devices that make possible ...
