Essential Information About Transistors
A transistor is a solid-state device made from a semiconducting material that is often used in the controlling or the amplification of electric current.Transistors come in arrays or packages called integrated circuits.Due to the extreme versatility that transistors do pose, they have become most preferred by industries as compared to vacuum tubes.
Transistors were first used commercially in the making of telephone switches for offices. After transistors were used in hearing aids, that is when most individuals got to know about transistors in 1952. Today, transistors and their varieties can be found in televisions, tape recorders, radios, burglar and fire alarms, video games, handheld calculators and in all the different kinds of controls from speed controls that are found in motors and drills to light dimmers.
After so many years of research and technological advancement, scientists discovered transistors in 1948. The world of electronics would be revolutionized after the discovery of transistors. As a matter of fact, this has come to pass. However, scientists did not stop there, they are still researching about surface science, crystal growth, solid state diffusion and other transistor disciplines.
The invention of the point-contact transistor was discovered by John Bardeen and Walter H. Brattain who worked for the Bell telephone laboratories. But William Shockley who was also their colleague at bell telephone laboratories was responsible for the invention of the commercially successful junction transistor. These three guys were jointly awarded the 1956 Nobel Prize in physics for their outstanding work.
Due to the high demand for new electronic components, there was a need to create new technologies to suit the different disciplines and techniques. As such, some of the transistors that were produced included the grown-junction germanium, the point-contact germanium, the alloy-silicon based and the surface germanium, as well as the field effect transistors, also referred to as the FET, and the junction field effect transistor abbreviated as JFET.
Most transistors devices undergo the planar process which involves building individual components of transistors and later connecting them. During this process, FET and silicon MOS components are added. Currently, there are variations of transistors which include the thyristor commonly known as the Silicon Controlled Rectifier (SCR) and the triacs which regulate high-current and control industry.
Irrespective of whether you are looking for NPN, PNP, Super Beta or Log Conformance, you should find an electronic manufacturing company that will provide you with the best transistor. The only thing you ought is to research about these companies and choose one that guarantees to build quality transistors that will match your needs.
