Facts About Transistors
A semiconducting material is used in the making of a solid state device called a transistor that is often used in the amplification or control of electric current. Integrated circuit is a collection of transistors.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. In fact, transistors have transformed the world of electronics. 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.
John Bardeen and Walter H. Brattain both of Bell telephone laboratories jointly worked together to invent the point-contact transistor. The two technicians discovered the junction transistor, but this time, they were assisted by William Shockley who also worked at Bell Telephone Laboratories. In 1956; they were awarded the Nobel Prize in Physics for their commendable job.
The world of electronics was swiftly growing and as a result semiconductors manufacturers needed to build modern technologies to match the variant disciplines and techniques. The bunch of transistors 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.
There are so many semiconductor manufacturing companies that you can find online that can create the kind of transistor you want even if it is the NPN, PNP, Super Beta or Log Conformance transistors. 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.
