The darlington configuration is two transistors connected in such a way that the gain (hFe) of the pair is higher than either transistor taken individually. The two collectors are connected together, and used as the collector of the pair. The base of the first transistor is the base of the pair. The emitter of the first transistor is connected to the base of the second transistor. The emitter of the second transistor is the emitter of the pair. Sometimes there is a resistor between the second base and the second emitter, so as to stabilize the pair in certain conditions. Typically, you multiply hFe's in darlington configuration, so if each transistor had an hFe of, say, 100, then the hFe of the pair would be 10,000.

Why transistor burns?
If inceres the base voltage of transistor them it may be burn . The base volt may be 0.8v to 1.8 If it use as a amplifier
Please Suggest equivalent transistor for AC 128.but it should not germanium transistor?
There are none. Germanium transistors are never equivalent to silicon.
Is a glacier composed of cells?
Glaciers are not composed of cells; they are composed of H2O molecules. Only living things, such as plants and animals, are composed of cells.
What did J Bardeen WH Brattain and W Shockley created?
The transistor
What type bacteris that have a cell wall composed?
the cell wall is not composed of bacteri it is composed of cellulouse
How do darlington transistors work?
A Darlington transistor it may contain one or more transistor in its case. the purpose is to amplify current by beta multiplication.
What is darlington configuaration?
A Darlington pair uses two transistors connected to behave as a single transistor with a very high current gain (beta). Transistor-1 has its collector connected to the collector of transistor-2. Transistor-1 has its emitter connected to the base of transistor-2. The base of transistor-1 with the emitter and collector of transistor-2 is used as a single transistor.
What is composite transistor?
A Darlington transistor is a composite transistor. The definition is a combination of two or more transistors that have the purpose of increasing the current gain.
Circuit diagram for darlington pair transistor?
A Darlington pair is two transistors connected to give a very high current gain
What is the advantage of darlington transistor to an ordinary bipolar junction transistor?
higher current handling / heat dissipation This is not really true as those are not singular characteristics of darlingtons. The major characteristics of a darlington is high gain, typically ranging from over 100 to 1000. And since there are essentially two transistors in the case of a darlington and the base of a darlington is connected to the base of the first transistor whose emitter is connected to the base of the second (power or output) transistor, the forward voltage drop from the base to the emitter of the darlington is approximately 2 times the forward voltage drop of a single transistor. it is a beta multiplier therefore it has higher emitter current capability and it not a hi gain per say just higher current capability as opposed to a regular transistor. usage is for an emitter follower which has no voltgage gain at all.
What element makes transistor?
A transistor is mainly composed of silicon and germanium
Why darlington pair is also known as superbeta transistor?
I also don't know..plz....help me...
What is TIP transistor?
TIP120/TIP121/TIP122 NPN Epitaxial Darlington Transistor • Medium Power Linear Switching Applications • Complementary to TIP125/126/127
What is the working of a Darlington amplifier?
it is a combination of two transistors connected in series. the emitter of transistor t1 is connected to the base of transistor t2 . now the total circuit acts as a single transistor. this combination will gives high gain, as the gain is multiplied.
What are the advantages of darlington pair?
A darling ton is a beta current multiplier. it output can be used to drive low impedance device
What is TIP122?
TIP120/TIP121/TIP122 NPN Epitaxial Darlington Transistor • Medium Power Linear Switching Applications • Complementary to TIP125/126/127
