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 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.
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 agreed that the invention of transistors would revolutionize the communications and electronics space. This has so far been true. However, scientists did not stop there, they are still researching about surface science, crystal growth, solid state diffusion and other transistor disciplines.
John Bardeen and Walter H. Brattain both of Bell telephone laboratories jointly worked together to invent the point-contact transistor. The two technicians discovered the junction transistor, but this time, they were assisted by William Shockley who also worked at Bell Telephone Laboratories. 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. 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.
Most transistors devices undergo the planar process which involves building individual components of transistors and later connecting them. Some of the components added during this procedure include the FET and Silicon MOS. 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.
Irrespective of whether you are looking for NPN, PNP, Super Beta or Log Conformance, you should find an electronic manufacturing company that will provide you with the best transistor. 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.
