No. The NPN transistor is a semiconductor crystal that was "doped" with n-type dopant, then p-type dopant, and then n-type dopant during manufacture. Just the opposite is true for the PNP transistor. Once it's made, it can't be "unmade" to change it.
No.
pnp and npn transistor
BT169 is neither an NPN nor a PNP transistor. BT169 is a thyristor, otherwise known as a silicon controlled rectifier.
no
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.
NPN and PNP are transistor types. The difference in the way the layers of semiconductor material are doped with impurities.
NPN, PNP only classified to BJT, while FET classified as P-channel , N-channel
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.
silicon ang germanium there are two types of transistor \ 1. PNP 2. NPN silicon ang germanium there are two types of transistor \ 1. PNP 2. NPN
Switching is faster in NPN transistor than PNP. Because movement of electrons is faster than holes.
There is no difference they perform the same functions.
Two, either in NPN or PNP transistors
A PNP transistor has no advantage or disadvantage over an NPN transistor in its ability as an amplifier. Rather, the current-handling capacities of the transistor determine if it's usable as an amplifier.
