tranzistorid

Tranzistorid, a plural form derived from "transistor," refers to semiconductor devices used to amplify or switch electronic signals and electrical power. These fundamental building blocks of modern electronics revolutionized technology after their invention in 1947. Transistors operate by controlling the flow of current through a semiconductor material using a small electrical signal applied to a control terminal. This ability to manipulate current allows them to perform various functions, from simple on/off switching to complex amplification of signals in radios, computers, and countless other electronic devices. The development of transistors led to miniaturization and increased efficiency compared to their predecessor, the vacuum tube, paving the way for the digital age. There are several types of transistors, with the most common being bipolar junction transistors (BJTs) and field-effect transistors (FETs), each with distinct operating principles and applications. Their widespread use and critical role in modern technology make them indispensable components in almost every electronic circuit.
