DETROIT -- An estimated 208,000 electric vehicles are being recalled by Hyundai and Kia because of an issue with a transistor that can lead to a loss of drive power. According to the Associated Press, ...

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 ...

Engineers at the US National Institute of Standards and Technology (NIST) believe there is a fundamental flaw in the understanding of transistor noise. The engineers add that, unless the problem is ...

A previous Design Idea describes a circuit that uses an astable multivibrator to drive an LED (Reference 1). The circuit in Figure 1 uses a simpler alternative approach. The circuit uses a 2N3904 NPN ...
