Different between power transistor and transistor that used in small signal?

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.


What is the minimum voltage required to turn on a pnp transistor?

If it's a germanium transistor, 0.3 volts. If it's the more common silicon transistor, slightly more than 0.6 volts.


Working of npn transistor?

N-p-n transistor is made by sandwiching thin layer of p-type semiconductor between two layers of n-type semiconductor. It has three terminals, Emitter, Base and collector. The npn transistor has two supplies, one is connected through the emitter base and one through the collector base. The supply is connected such that emitter-base are forward biased and collector base are reverse biased. It means , Base has to be more positive than the emitter and in turn, the collector must be more positive than the base. The current flow in this type of transistor is carried through movement of electrons. Emitter emits electrons which are pulled my the base as it is more positive. these end up in the collector as it is yet more positive. In this way, current flows in the transistor. Transistor can be used as an amplifier, a switch etc.


What is power transistor briefly?

One capable of being used at power rating of greater than about 10 watts, and generally requiring some means of cooling


How many diodes in a transistor?

There are two semiconductor junctions. Transistors are designated as NPN or PNP and a diode is an NP or PN junction depending on direction of current flow. However, the function of a transistor is different than two back to back diodes.

What characteristics made the transistor better than the vacuum tube?

There were obvious differences between the trasisitor and the vacum tube. The transistor was faster, more reliable, smaller, and much cheaper to build than a vacuum tube. One transmisor was the equivalent 40 vacuum tubes. They also didn't produce heat compare it to a vacuum tubes. Conduct electricity faster and better than vacuum tubes.


Why CE transistor is more temperature senstive than CB transistor?

In CE transistor volteage divider biasing is used, which is independent of temperature and other parameters.

What compensation technique is better than other techniques in transistor biasing?

That would depend on your application. If there was a singke best way, that would be the only method used.


What is the probability that the transistor will last more than 550 hours?

The answer depends on the type of transistor, how intensively it is used as well as the manufacturer.

Is Intel Core i5 powerful than core 2 Quad processors?

Yes. In simple. Better, newer, more power efficient, smaller transistor sizes etc.


How many states does a transistor have?

A transistor can be in three conditions or states. It can be active (at a voltage higher than the emitter), in saturation or cut off (no current).


Can fet be used as a transisitors?

No. The Field Effect Transistor is a different technology than the Bipolar Junction Transistor. That cannot substitute for one another.


Can you replace mosfet with an bjt transistor?

A MOSFET (metal oxide semiconductor field effect transistor) can be used INSTEAD of a BJT (bypolar junction transistor, so transistor is redundant in your question), if the circuit in question is modified to allow it and the MOSFET is chosen appropriately. BJT's will usually have a higher intrinsic gain, but have lower input resistance. Also a BJT in general will work better at higher frequencies than a MOSFET (unless you choose a high frequency MOSFET) due to the capacitive nature of MOSFETs.


What is multi emitter transistor?

A bipolar junction transistor with 2 or more emitters. The most common use of these was in the input section of transistor transistor logic (TTL) gates. They offered significantly higher speed and used less area on the IC chip than the diodes used in the input section of the diode transistor logic (DTL) gates that came earlier. This made TTL ICs both faster and cheaper than the DTL ICs which soon became obsolete.


Why do you have to connect a resistor to collector of transistor?

Type your answer here... to properly bias the junction for current flow thru the transistor. The voltage potential must be different on the base than the collector
