Essential Information 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 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.
In the past, transistors were first placed in offices telephone switches. 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.
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. As a matter of fact, this has come to pass. 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.
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. These three guys were jointly awarded the 1956 Nobel Prize in physics for their outstanding work.
With the technological advancement, there arose the different disciplines and process that brought about the invention of new transistors. 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.
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.
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. 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.
