Transistors come in different flavors. Tubes used an electric field to regulate current flow, and researchers wanted to find something that worked the same way without the drawbacks like vacuum and ...

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.

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, ...

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 ...

A transistor fabricated from the crystalline phase of an organic semiconductor material could provide a path to improved switching speeds — rivalling those of devices built from inorganic materials ...
