Transistors

A transistor is a basic semiconductor device, which has three terminals and three sequentially connected zones with different doping, which determines the transistor’s polarity (PNP or NPN). There is a variety of transistor types, based on two main groups, namely: bipolar junction transistors and field-effect transistors. The most important feature of bipolar transistors is that they have a carrier injection through the PN junction and their operating power is determined by two types of carriers, hence their name – bipolar. FETs don’t have a carrier injection through the junction and their operating power is determined either by electrons or by holes, for this reason FETs are sometimes called unipolar transistors.

Transistors can be used for amplifying, switching and converting electronic signals. Transistors are widely used and are active elements in almost all modern electronic devices. They are often assembled in integrated circuits and microchips.

In general, the method of operation of the transistor is based on its ability to convert voltage or current impulse transmitted through a pair of terminals. The output voltage or current going through the other pair of terminals is higher or respectively lower.
Transistors are also widely used in the production of inverter welding and supply devices.
