This tester is primarily meant to test bipolar transistors. It can indicate the type of the transistor as well as identify its base, collector and emitter pins. The circuit is very simple. The ...

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 ...

The ISL73096EH is a radiation hardened ultra high frequency NPN/PNP transistor array. It contains three NPN transistors and two PNP transistors on a common substrate. The device covers all of the ...

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 ...

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 ...
