Identify Transistor Pin-outs
Which Pin Is Which on a BJT?Use this chart to find which pin is the base on a bipolar transistor and at the same time get a good idea of whether the transistor is faulty or good.(Don´t test FETs in this way though - handling FET pins can destroy the transistor!).
Follow tests 1 - 3 then decide from the result which of the four arrows to follow. You may have to go through the test sequence more than once to make your diagnosis.
The emitter and collector pins are the outer pins, and on a metal can transistor, the emitter pin will be closest to the bit of metal that sticks out. For transistors with a flat side, the pins could be either Emitter, Base, then Collector with the flat side facing toward you, or Collector, Base, Emitter, or very rarely something else, so the datasheet should be consulted (search online for whatever is marked on it). On power transistors, it is Emitter, Collector, Base, with the metal tab facing you.
Basically, in transistor, the signal is transferred from low resistance circuit to the high resistance circuit. So it is called transfer+resistor=Transistor.Transistors are widely used in different types of switching, amplifiers, oscillators and integrated circuits.Based on the applications, the types of the transistors are as given below:General purpose transistors, Low frequency transistors, High frequency transistors, Power transistors, Switching transistors, Field Effect Transistors, MOSFET, Uni-junction Transistors, Bi junction transistors, Photo transistor, High power transistors, Complementary pair, Darlington amplifier, Video and R.F. amplifier, Ultrahigh frequency and microwave, Insulated gate bipolar transistors, Static induction transistors.More their to know about transistors are as given below:History of invention, Time-line throughout, Basic construction, Bias arrangement, working, Various currents in transistors, Basic transistor amplifier, Configurations, Characteristics, Current gain and relation among them, D.C. load line, Operating point, Biasing of transistor, stability factor, specifications and ratings, testing, colour coding, identification of transistor using multimeter, h-parameter of transistor, particular applications etc...
With lots of FETs (for CMOS ICs) or ordinary transistors, you can make a circuit that will function like the IC. These are manufactured by making silicon chips, which are placed inside a plastic/ceramic carrier, which has pins.
Power transistors are transistors that are used in high-power amplifiers and power supplies.
Transistors are made out of semiconductors, yes.
Silicon and germanium are the elements used in transistors
Silicon and germanium are the elements used in transistors
The primary reason that NPN transistors are used more often than PNP transistors is that they usually operate faster (at higher frequencies) because the mobility of the current carriers in NPN transistors (electrons) is much higher than that of the current carriers in PNP transistors (holes).

There were vacuum tubes before transistors
yes, Mobile phones are having transistors.
