Facts 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. Integrated circuit is a collection of transistors.Transistors are used in various applications, and that is why they have turned out to be the most commonly used components in the word of electronics.
In the past, transistors were first placed in offices telephone switches. 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. Everyone thought after the creation of transistors the electronic world would be transformed. 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.
It took two scientists from Bell telephone laboratories to create the point-contact transistors- John Bardeen and Walter H. Brattain. But William Shockley who was also their colleague at bell telephone laboratories was responsible for the invention of the commercially successful junction transistor. Under the Physics category, these three scientists were awarded the Nobel Prize in 1956 for having discovered the most important electronic component.
With the technological advancement, there arose the different disciplines and process that brought about the invention of new transistors. In this regard, some of the transistors that were built include 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.
One of the processes used during the creation of transistors is known as planar silicon, and here semiconductor manufacturers build each part of the transistor and later connect 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. 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.
