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 come in arrays or packages called integrated circuits.Due to the extreme versatility that transistors do pose, they have become most preferred by industries as compared to vacuum tubes.
Transistors were first used commercially in the making of telephone switches for offices. Most consumers interacted with transistors in 1952 when they were used in making hearing aids. Currently, you will not only find transistors in televisions, tape recorders, radios, burglar and fire alarms, but you will also find them in 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 agreed that the invention of transistors would revolutionize the communications and electronics space. 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.
The invention of the point-contact transistor was discovered by John Bardeen and Walter H. Brattain who worked for the Bell telephone laboratories. 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.
The world of electronics was swiftly growing and as a result semiconductors manufacturers needed to build modern technologies to match the variant disciplines and techniques. 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. 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.
There are so many semiconductor manufacturing companies that you can find online that can create the kind of transistor you want even if it is the NPN, PNP, Super Beta or Log Conformance transistors. 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.
