All You Need to Know 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.Transistors come in arrays or packages called integrated circuits.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. 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.
Due to the great demand for new technologies in 1948, scientists created the first transistor during that year. Everyone thought after the creation of transistors the electronic world would be transformed. This has so far been true. 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. 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.
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.
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. In addition to that, there are numerous types of transistors one of them being the thyristor transistor, which is referred to as the Silicon Controlled Rectifier (SCR) and the second type is known as the triacs which dominates the 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 only thing you ought is to research about these companies and choose one that guarantees to build quality transistors that will match your needs.
