All You Need to Know 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. 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 thought after the creation of transistors the electronic world would be transformed. 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. 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. 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. Some of the components added during this procedure include the FET and Silicon MOS. 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.
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 bottom line is to check their industrial experience and how reputable they are in delivering quality transistors that suit the customers’ needs and requirements.
