BC547is an NPN bi-polar junction transistor. A transistor, stands for transfer of resistance, is commonly used to amplify current. A small current at its base controls a larger current at collector & emitter terminals.
BC547is mainly used for amplification and switching purposes. It has a maximum current gain of 800. Its equivalent transistors are BC548 and BC549.
The transistor terminals require a fixed DC voltage to operate in the desired region of its characteristic curves. This is known as the biasing. For amplification applications, the transistor is biased such that it is partly on for all input conditions. The input signal at base is amplified and taken at the emitter. BC547 is used in common emitter configuration for amplifiers. The voltage divider is the commonly used biasing mode. For switching applications, transistor is biased so that it remains fully on if there is a signal at its base. In the absence of base signal, it gets completely off.

Bc100 is an npn transister. if we know vlsi/cmos u will come to know about npn & pnp configurations.
The active region of a transistor is when the transistor has sufficient base current to turn the transistor on and for a larger current to flow from emitter to collector. This is the region where the transistor is on and fully operating.
Power transistor can conduct large amount of currents through it, more than small signal transistor. power transistor has a vertical structure and small signal transistor has horizontal structure.In power transistor quasi saturation region is present which is absent in the small signal transistor. In power transistor there is a inculsion of drift layer which is not there in the small signal transistor. Power dissipation is less in power transistor and it is more in small signal transistor. b.v.polytechnic,vasai pushkar vaity.

Transistors have many characteristics and they most certainly require voltages to be a certain polarity if they are to work properly. There are two main types of transistor: PNP and NPN. They are identical except that all polarities are reversed on one compared to the other. There are many books and online resources that describe transistors but here is a very brief note about transistor operation. Each transistor has a base, a collector and an emitter. When a small current is passed from the base to the emitter, a larger current will pass from the collector the the emitter. With an NPN transistor, the base needs to be positive with respect to the emitter and the collector also has to be positive with respect to the emitter for the transistor to work. A PNP transistor is reversed, where both the base and the collector need to be negative with respect to the emitter to operate. Therefore, transistors do indeed have a polarity, even if it is more complex that some other devices. Disclaimer: The above description of transistor operation is greatly simplified and there are operational modes that are outside the conditions described. Please don't use the above description as a definitive guide to transistor behaviour.
A silicon transistor is a transistor made of silicon.
The active region of a transistor is when the transistor has sufficient base current to turn the transistor on and for a larger current to flow from emitter to collector. This is the region where the transistor is on and fully operating.
A Unijunction Transistor is a transistor that acts solely as a switch.
