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. Transistors are packaged together to form an integrated circuit.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.
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.
Transistors were invented in 1948, and this was after years of research that was necessitated by the blossoming growth in science and technology. 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. 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. Under the Physics category, these three scientists were awarded the Nobel Prize in 1956 for having discovered the most important electronic component.
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.
The process by which individual components of transistors are brought together during the creation process is known as the planar process. 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. The bottom line is to check their industrial experience and how reputable they are in delivering quality transistors that suit the customers’ needs and requirements.
