These are analogous to the terminals on a bipolar transistor, in that the source fulfills a similar role to the emitter, the gate to the base, and the drain to the collector.

There are numerous differences between NPN and PNP transistors, and even though both are bipolar junction transistors, the direction of current flow is the name of the game.

The purpose of a transistor is to control the flow of current from one point to another. To accomplish this, we must construct a two-junction device known as a bipolar transistor. Both P (positive) ...

What does bipolar transistor actually mean? Find out inside PCMag's comprehensive tech and computer-related encyclopedia.

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 ...

"NPN" and "PNP" refer to the arrangement of the different types of semiconductor material in a Bipolar Junction Transistor (BJT). In an NPN transistor, there's a layer of p-type semiconductor material ...

PNP transistors and n-channel transistors function similarly to “signal turns switch on” relays and tubes; likewise NPN transistors and p-channel transistors function similarly to “signal ...

Solid-state device technologies, which are available to the amplifier designer, fall, broadly, into three categories: bipolar junction transistors (BJTs) ...

Q1 can be any npn bipolar transistor. A high-gain transistor is preferred because it lowers the base current, allowing a larger R and smaller C.

Nexperia has announced 20 bipolar power transistors in 2 x 2mm DFN2020D-3 packaging, half of them automotive-qualified. The span 50 and 80V ratings, 1 to 3A currents and both npn and pnp polarities.
