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 2SA1648 is a PNP silicon epitaxial transistor featuring fast switching speed for high current control. It features low collector saturation voltage, as well as high DC current gain and excellent ...

In a nutshell: Back in 2021, a team from the Massachusetts Institute of Technology made waves by creating an entirely new type of ferroelectric material. Now, those same researchers have one-upped ...

A new way to switch transistors could overcome the power consumption and undesirable current leakage problems encountered in conventional nanoscale field-effect devices. The new technique, which works ...
