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 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. But it is after 1952 that most people got hold of transistors since they were used to make 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 agreed that the invention of transistors would revolutionize the communications and electronics space. 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.
John Bardeen and Walter H. Brattain both of Bell telephone laboratories jointly worked together to invent the point-contact transistor. 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. In 1956; they were awarded the Nobel Prize in Physics for their commendable job.
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.
Most transistors devices undergo the planar process which involves building individual components of transistors and later connecting them. At this stage, FET, and silicon MOS elements are included. 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.
