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 are packaged together to form an integrated circuit.Since transistors can be used in different places, they have become some of the essential electronic elements across the globe.
Transistors were first used to make office telephone switches. Most consumers interacted with transistors in 1952 when they were used in making hearing aids. Today, transistors and their varieties can be found in televisions, tape recorders, radios, burglar and fire alarms, video games, handheld calculators and in all the different kinds 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. 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.
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. Under the Physics category, these three scientists were awarded the Nobel Prize in 1956 for having discovered the most important electronic component.
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.
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. During this process, FET and silicon MOS components are added. 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.
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 only thing you ought is to research about these companies and choose one that guarantees to build quality transistors that will match your needs.
