SL100


Why is BC547 better than SL100 transistor?

Bc100 is an npn transister. if we know vlsi/cmos u will come to know about npn & pnp configurations.


What is description of Bc547 transistor?

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.


What is BC in BC547?

Before Christ


Why transistor is called so?

transistor. This word is a blended form of transfer of resistor. The legs of transistor (collector, emitter,base) transfer the resistance. So it is called as transistor


Why RC couple is called transistor?

Its not!


Why transistor is called as bi-polar device?

Transistor is called Bi-Polar device because the current can be flow due to electron and holes, hence it is called bipolar.


What is the meaning of the term BC in bc547?

Before Christ as AD stands for After death


What does bc in bc547 mean?

B for siliconC low power audio frequency


Why transistor is called transfer of resistor?

Transistor=Transfer+Resistor. When Transistor operates in active region its input resistance is high and output resistance is low. So,We can consider transistor as a device which transfers its resistance from high to low. And by this property transistor amplifies input signal.


What is unmodulated signal from a transistor is called?

When the out from a transistor is the exact replic of the input signal then it is called unmodulated signal i e. there will not be any change in frequency voltage power etc


Why is MOSFET called IGFET?

MOSFET is Metal Oxide Semiconductor Field Effect Transistor. IGFET Insulated Gate Field Effect Transistor. But these expressions are practically synonyms.
