On Oct. 3, 1950, three Bell Labs scientists received a patent for a "three-electrode circuit element" that would usher in 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 ...

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 ...

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 has introduced a series of miniature NPN and PNP transistors for MOSFET gate driving in latest generation power supplies. ZXTN and ZXTP transistors The first bipolars to be ...

The handedness or “chirality” of electrons affects how current flows in graphene transistors, according to new work done by researchers in the UK and Russia. The team’s findings could help to make ...

A versatile signal-conditioning circuit for use with with programmable logic converters or controllers that can accept only one input polarity. Matching a sensor interface with a programmable logic ...
