pnp is more useful than npn
pnp and npn transistor
how to use transistor a1015
A PNP transistor is designed for signal amplification, switching, etc., just like the NPN transistor but using inverted (opposite) voltage polarities.
The main difference is that a PNP transistor uses "holes" as carriers and an NPN transistor uses electrons as carriers (It is to be remembered that the flow of current is always in the direction opposite to that of the flow of electrons).
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.
BT169 is neither an NPN nor a PNP transistor. BT169 is a thyristor, otherwise known as a silicon controlled rectifier.
The PNP transistors conducts when there is no signal at base (0V or grounded), when base current is increased the conduction of PNP transistor decreases.
it doesn't have to be. depends on design of amplifier using transistor.
beacause i dont know how to use pnp transistor so its better u also use a npn transistor. if you dont want to use a npn transistor then dont use a transistor. haha as simple as that. isn't it? " there is no charge for awesomness !!"
if the arrow of emitter terminal is outwards is called npn transistor otherwise if the arrow of the emitter terminal of a transistor is inwards is called pnp transistor A/ On a diagram a NPN the arrow will indicate the current flow as the emitter a line is the base. An pnp will follow the same principle With a meter you may certify this principle by noting leads polarity
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.
You can use a PNP or an NPN transistor in a fire alarm circuit. Both will work. It all depends on how you want to energize the alarm, and with what polarity of signal.
NPN and PNP are different types of transistors, used for slightly different jobs.
An AS162 transistor is a type of PNP transistor commonly made of germanium. This is an older kind of transistor that was often found in power amplification circuits.
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
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.
One may purchase a PNP transistor from a local electronics hobby shop or a chain such as Radio Shack. The website "Mouser" also has transistors and downloadable data sheets for them.
pnp transister in common emitter mode
PNP Positive Negative Positive, is a type of Transistor. I don"t know of military applications.
higher current carrier mobility, resulting in faster speed.
