Over the recent weeks here at Hackaday, we’ve been taking a look at the humble transistor. In a series whose impetus came from a friend musing upon his students arriving with highly developed ...

ThermalTrak integrates power output transistors with thermal bias diode. One of the major design concerns in the output section of a typical class AB audio amplifier is output bias and stability over ...

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 ...
