The transistor is an electronic equipment. It is made through p and n type semiconductor. When a semiconductor is placed in center between same type semiconductors the arrangement is called transistors. We can say that a transistor is the combination of two diodes it is a connected back to back. A transistor is a device that regulates current or voltage flow and acts as a button or gate for electronic signals. Transistors consist of three layers of a semiconductor device, each capable of moving a current.
Bipolar Junction Transistor (BJT)
Bipolar Junction Transistors are transistors which are built up of 3 regions, the base, the collector, and the emitter. Bipolar Junction transistors, different FET transistors, are current-controlled devices. A small current entering in the base region of the transistor causes a much larger current flow from the emitter to the collector region. Bipolar junction transistors come in two major types, NPN and PNP. A NPN transistor is one in which the majority current carrier are electrons. Electron flowing from the emitter to the collector forms the base of the majority of current flow through the transistor. The further types of charge, holes, are a minority. PNP transistors are the opposite. In PNP transistors, the majority current carrier is holes.
Field Effect Transistor
Field Effect Transistors are made up of 3 regions, a gate, a source, and a drain. Different bipolar transistors, FETs are voltage-controlled devices. A voltage placed at the gate controls current flow from the source to the drain of the transistor. Field Effect transistors have a very high input impedance, from several mega ohms (MΩ) of resistance to much, much larger values. This high input impedance causes them to have very little current run through them. (According to ohm’s law, current is inversely affected by the value of the impedance of the circuit. If the impedance is high, the current is very low.) So FETs both draw very little current from a circuit’s power source.
Transistor Applications
The appropriate application of power semiconductors requires an understanding of their maximum ratings and electrical characteristics, information that is presented within the device data sheet. Good design practice employs data sheet limits and not information obtained from small sample lots. A rating is a maximum or minimum value that sets a limit on device’s ability. Act in excess of a rating can result in irreversible degradation or device failure. Maximum ratings signify extreme capabilities of a device. They are not to be used as design circumstances.
A characteristic is a measure of device performance under individual operating conditions expressed by minimum, characteristic, and/or maximum values, or revealed graphically.
Thus, this is all about what is a transistor and different types of transistors and its applications.

NPN is one of the two types of Bipolar Junction Transistors (BJT). The NPN transistor consists of two n-type semiconductor materials and they are separated by a thin layer of p-type semiconductor. Here the majority charge carriers are electrons and holes are the minority charge carriers.
