Ever since the development of the first working transistors in 1947, the electronics industry has experienced tremendous growth in numerous ways. For instance, transistors allowed for the ...

The two types of standard transistors are PNP and NPN which differs in circuit symbols. The layers of semiconductor material used to make the transistor are denoted by the letters. To keep a straight ...

Manufacturing companies, particularly those that mass-produce electronic circuits, work pretty much around bipolar junction transistors, like PNP and NPN. However, choosing between these two BJTs can ...

Based on the knowledge developed in the previous tutorials, we now start the study of this important electronic component. We have thus created a PNP transistor. Figure 1: A PNP transistor. The size ...

Most bipolar junction transistors and field-effect transistors (FETs) have three terminals. In the BJT symbol, the base lead is perpendicular to and lands at the midpoint of a short line segment ...

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 ...

Transistors are made up of semiconductor material which is most commonly used for amplification or switching purpose, although they can also be used for controlling the flow of voltage and current.

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 ...

The transistor is probably the most important invention in electronic engineering and the basis for nearly all integrated circuits (ICs). The transistor is a three-terminal electronic device that can ...

The first bipolar junction transistor was invented in 1947 at Bell laboratories. “Two polarities”is abbreviated as bipolar, hence the name Bipolar junction transistor. BJT is a three terminal device ...
