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.Transistors come in arrays or packages called integrated circuits.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. Most consumers interacted with transistors in 1952 when they were used in making hearing aids. But these days transistors are being used in televisions, tape recorders, radios, burglar and fire alarms, video games, handheld calculators and in all the different types 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 agreed that the invention of transistors would revolutionize the communications and electronics space. This has so far been true. Scientists have put more of their efforts into doing more research into 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. The two technicians discovered the junction transistor, but this time, they were assisted by William Shockley who also worked at 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.
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.
The process by which individual components of transistors are brought together during the creation process is known as the planar process. 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. 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.
