Facts About Transistors
A transistor which is used in the amplification and the control of electric current is a solid state device which is created from a semiconducting material. Integrated circuit is a collection of transistors.Since transistors can be used in different places, they have become some of the essential electronic elements across the globe.
Transistors were first used commercially in the making of telephone switches for offices. Most consumers interacted with transistors in 1952 when they were used in making hearing aids. 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. Nonetheless, scientists are still putting more efforts to discover more about surface science, crystal growth, solid state diffusion and other areas that are related to the study of transistors.
The invention of the point-contact transistor was discovered by John Bardeen and Walter H. Brattain who worked for the Bell telephone laboratories. However, the creation of the commercial junction transistor was made possible by the two with the help of William Shockley who also worked at the Bell Telephone Laboratories. In 1956; they were awarded the Nobel Prize in Physics for their commendable job.
With the technological advancement, there arose the different disciplines and process that brought about the invention of new transistors. 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. At this stage, FET, and silicon MOS elements are included. These days, different types of resistors consist of the thyristor which is usually referred to as the Silicon Controlled Rectifier abbreviated as SCR and triacs which controls high-current and control industry.
So, if you are looking for a transistor, you can search online for the best semiconductor manufacturing companies who can create the kind of transistor you are looking for-be it NPN, PNP, Super Beta or Log Conformance. All you have to do is examine how long the company has been in operation and if it holds a good reputation in creating the best transistors that align with clients’ needs.
