Is the pnp transistor in common collector can be replaced with npn transistor?
No. The PNP and NPN transistors are exactly opposite each other in polarity. You cannot just replace one for the other without redesigning the circuit.
What is difference between npn ans pnp transistor?
NPN and PNP transistors function in essentially the same way. The power supply polarities are simply reversed for each type. The only major difference between the two types is that the NPN transistor has a higher frequency response than the PNP-because electron flow is faster than hole flow. Therefore high frequency applications will utilize NPN transistors.
Inputoutput and transfer characteristics of pnp and npn transistor in common base configuration?
result of output characteristics of npn transister in CB mode
Why are npn transistors used more often than pnp transistors?
The primary reason that NPN transistors are used more often than PNP transistors is that they usually operate faster (at higher frequencies) because the mobility of the current carriers in NPN transistors (electrons) is much higher than that of the current carriers in PNP transistors (holes).
How many pn junction does transistor contain?
Two, either in NPN or PNP transistors
What are the functions and empowerment of PNP as per PNP laws?
pnp and npn transistor
कैसे NPN ट्रांजिस्टर PNP ट्रांजिस्टर से अलग है?
diff. between npn and pnp transristor
Difference between NPN and PNP?
NPN and PNP are transistor types. The difference in the way the layers of semiconductor material are doped with impurities.
Is BT169 a npn or pnp transistor?
BT169 is neither an NPN nor a PNP transistor. BT169 is a thyristor, otherwise known as a silicon controlled rectifier.
Field-effect transistor NPN or PNP?
NPN, PNP only classified to BJT, while FET classified as P-channel , N-channel
What kind of semiconductor is produced by adding indium in semiconductor crystals pnp or npn?
pnp
Why you use NPN transistors rather than PNP?
Switching is faster in NPN transistor than PNP. Because movement of electrons is faster than holes.
Is PNP sourcing or sinking?
PNP is sourcing. NPN is sinking. You generally connect NPN to ground and your PLC(or any load)input. With PNP you connect to V+ and to your PLC. Your PLC (load) should have the same ground or V+. Sourcing (PNP) provides a path to +24DC generally. Sinking (NPN) provides a path to 0V DC.
Can be replace npn transistor series regulator with pnp?
no
Why PNP and NPN are used in direct coupling?
To save a decoupling capacitor & biasing resistors for the PNP.
Is it emitter-base junction should be reversed for both npn and pnp transistors acts as a amplifiers?
no, the emitter base junction should be foward for both npn and pnp to act as amplifiers.
How do you know if a transistor is a PNP or an NPN?
To know if a transistor is PNP or an NPN,the following should be verified:For a PNP transistor, the base-collector junction is forward biased while the base-emitter junction is reversed biased.For an NPN transistor, the base-emitter junction is forward biased while the base -collector junction is reversed biased.
