Facts 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. After transistors were used in hearing aids, that is when most individuals got to know about transistors in 1952. 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. In fact, transistors have transformed the world of electronics. 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. But William Shockley who was also their colleague at bell telephone laboratories was responsible for the invention of the commercially successful junction transistor. In 1956; they were awarded the Nobel Prize in Physics for their commendable job.

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.

One of the processes used during the creation of transistors is known as planar silicon, and here semiconductor manufacturers build each part of the transistor and later connect them. At this stage, FET, and silicon MOS elements are included. Currently, there are variations of transistors which include the thyristor commonly known as the Silicon Controlled Rectifier (SCR) and the triacs which regulate 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.
