Bipolar junction transistor - Wikipedia

A bipolar junction transistor (BJT) is a type of transistor that uses both electrons and electron holes as charge carriers.In contrast, a unipolar transistor, such as a field-effect transistor, uses only one kind of charge carrier.A bipolar transistor allows a small current injected at one of its terminals to control a much larger current flowing between two other terminals, making the device ...

Choosing Transistor Replacements » Electronics Notes

Step by step instructions: Choose a transistor of the same polarity: The first major selection criterion is whether the transistor is PNP or NPN. Select a replacement transistor of the same material: Most transistors are either silicon or germanium. As bias voltages and other features are different it is necessary to select a replacement transistor with the same material.
