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 ...

Biasing an active device, such as a bipolar junction transistor (BJT), requires that you set the dc voltages and currents of the device. To optimize the desired result, you need various bias values.

This course presents in-depth discussion and analysis of metal-oxide-semiconductor field-effect transistors (MOSFETs) and bipolar junction transistors (BJTs) including the equilibrium characteristics, ...

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 ...

Offered in a 5-lead TO-264 package, the 15-A NJL1302D (pnp) and NJ3281D (npn) ThermalTrak bipolar power transistors incorporate an internal thermally matched bias diode to eliminate warm-up time, ...
