An additional third electrode (G - gate) runs along the channel, which, under the influence of the applied voltage, alters the conductivity of the channel and thus affects the flowing current. The principle of operation is simple: the semiconductor is equipped with two electrodes - source S and drain D - the current flows along a semiconductor path (the so-called channel). In field-effect transistors, the current flows through a semiconductor of a single conductivity type therefore the output current is a function of the control voltage. Of course, within each of these types there are additional sub-types of transistors (MOSFET, JFET, IGBT, etc.), but the key principle of operation is the same. This typology is crucial because it actually describes two basic types of transistors, which differ in their operating principle: field-effect (unipolar) transistors and bipolar transistors. The last two concern the materials used to make the transistors and the basic parameters and are not as important as the systematics described in the first point. Low or high power transistors, low or high frequency transistors.Germanium and silicon transistors for very high frequency applications (silicon carbide, gallium nitride, gallium arsenide). ![]() ![]() Transistors are classified according to several criteria, with the following being the most important: The replacement of large and energy-consuming electron tubes with these miniature components (nanometer-scale transistors), as is the case with computer microprocessors, has accelerated the development of technology and brought us to our current level of civilization progress. The commercialization of transistors in the middle of the last century completely changed the development of all technologies, including electronics. The simplest answer is: a transistor is a 3-pin (sometimes 4-pin), semiconductor device with the ability to amplify electrical signals and to act as a current-controlling device. In this article, we will show you how to check the correct functioning of these electronic components. Like any other component, the transistor may also malfunction or be damaged. By replacing the electron tubes, they started the era of miniaturization of electronic devices and devices, which continues to this day. Transistors, developed in the middle of the 20th century, became the basis for the rapid development of electronics.
