After this not-so-recognized venture, William Shockley made a successful attempt of making a bipolar junction transistor by pressing together the wafers of semiconductor materials.Finally, in 1947 the efforts of john Walter and Bardeen a rough two-point contact device was made which was nowhere near to the modern of a bipolar junction transistor but it laid the foundation for the construction of a solid-state transistor when previously everything was vacuum!.So when scientists were done with controlling electrons inside a vacuum tube and its unruly behavior, they started devising other ways to run and control circuits.The vacuum tube triodes remained a hyped-up thing for almost half of a century, but they occupied large space and were less reliable in terms of usage, the other major drawback was the increase in complications related to current, voltage and whatnot just by increasing the number of vacuum triodes in the circuit.Prior to the bipolar junction transistors, vacuum tubes were used in electronic circuits which were highly expensive, those too were available in the form of a triode which was a three terminal device like a transistor back then.History of the bipolar junction transistor_ BJT "A bipolar junction transistor is a three-terminal semiconductor device which is made up of two PN junctions within its structure and is mainly used to amplify current"

So, let's get started.Ī BJT in its full form is written as bipolar junction transistor and we can define it as, In this article, we will go through the basics of the bipolar junction transistor including its meaning ,definition, types, characteristics, and applications. Today, we are about to discuss one of the most commonly known types of transistors which you might have heard of many times when reading about transistors, the transistor under study is none other than the “Bipolar Junction Transistor’’, also known as BJT. Hello friends, I hope this article finds you happy, healthy, and content.
