How transistors are named?
Bipolar junction transistors are the most commonly used type. To help identify them, transistors are labeled with number and letters on their casings. Transistors are labeled according to the numbering system that is used. The primary numbering systems are JIS, Pro Electron, and JEDEC.
What does transistor stand for?

Who discovered BJT?
physicist William Shockley
Invented by the physicist William Shockley in 1947, the BJT has gone through a number of iterations over the years.
What school did Gordon Moore go to?
California Institute of Technology1954
University of California, Berkeley1950San José State UniversitySequoia High SchoolCollege of Chemistry, University of California, Berkeley
Gordon Moore/Education
Education. Moore studied chemistry at the University of California, Berkeley (B.S., 1950), and in 1954 he received a Ph. D. in chemistry and physics from the California Institute of Technology (Caltech), Pasadena.
How did computers get so small?
In the late 1950’s, computers got smaller because one of its main components – the valve – was replaced by the much smaller transistor. These made computers far more reliable and therefore businesses took a much greater interest in them.
Why is pn junction called a diode?
A diode is called a diode because it has two distinct electrodes (i.e. terminals), called the anode and the cathode. A diode is electrically asymmetric because current can flow freely from the anode to the cathode, but not in the other direction.
What is biasing in a transistor?
Transistor Biasing is the process of setting a transistors DC operating voltage or current conditions to the correct level so that any AC input signal can be amplified correctly by the transistor.
What is a transistor and how does it work?
A transistor is a semiconductor device used to amplify and switch electronic signals and electrical power. It is composed of semiconductor material with at least three terminals for connection to an external circuit. A voltage or current applied to one pair of the transistor’s terminals changes the current through another pair of terminals.
What are the uses of a transistor?
Transistor, semiconductor device for amplifying, controlling, and generating electrical signals. Transistors are the active components of integrated circuits, or “microchips,” which often contain billions of these minuscule devices etched into their shiny surfaces.
What can a transistor be used as?
A transistor is used to amplify and switch electronic signals and electrical power. They are used in a variety of circuits and they come in many different shapes. You can use a transistor as a switch or you can use a transistor as an amplifier.
Are the two main uses of a transistor?
Some types of transistors are used primarily for switching applications. Others can be used for both switching and amplification . Still other transistors are in a specialty group all of their own, such as phototrransistors, which respond to the amount of light shining on it to produce current flow through it.
