What is P and N in transistor?
As we are aware that in PNP transistor, the P represents the polarity of the emitter terminal and N represents the polarity of the base terminal. In NPN, N represents the negatively charged coating of the material whereas P represents the charged layer.
Which is the symbol of transistor?

What type of transistor is a 3906?
The 2N3906 is a commonly used PNP bipolar junction transistor intended for general purpose low-power amplifying or switching applications. It is designed for low electric current and power and medium voltage, and can operate at moderately high speeds.
Is BC547 NPN or PNP?
NPN transistor
BC547 -> BC547 is a NPN transistor hence the collector and emitter will be left open (Reverse biased) when the base pin is held at ground and will be closed (Forward biased) when a signal is provided to base pin.
Can I use 2N2222 instead of BC547?
The 2N2222 and BC547 transistors are general-purpose transistors that are commonly used in electrical circuits; the BC547 transistor is one of the best transistor counterparts which can interchange with 2N2222 transistor.
Which is better NPN or PNP?
So n-p-n transistors are preferred as they amplify the signals. So the correct answer is that n-p-n transistors are preferred to p-n-p transistors because electrons have higher mobility than holes and hence high mobility of energy.
What does N stand for in NPN?
It’s easy to remember that NPN stands for Negative-Positive-Negative and PNP stands for Positive-Negative-Positive transistors. Let’s take a closer look at how NPN and PNP transistors work.
What is NPN type?
NPN transistors are a type of bipolar transistor with three layers that are used for signal amplification. It is a device that is controlled by the current. A negative-positive-negative transistor is denoted by the abbreviation NPN.
What is a symbol of NPN transistor?
NPN vs PNP Transistor
NPN Transistor | PNP Transistor | |
---|---|---|
Symbol | ||
Collector-emitter voltage | Positive | Negative |
Emitter arrow | Pointed out | Pointed in |
What is the difference between 2N3904 and 2N3906?
As people said that the basic difference between 2N3904 and 2N3906 is that former is NPN transistor and later is PNP.
What is BC557 transistor?
BC557 is a general-purpose transistor, used like an amplifier or a switch in electronic circuits. Its hFE ratings of this transistor range from 125 to 800 to make the transistor ideal by using like an amplifier within electronic circuits like audio signal amplification.
What is the use of 2N2222 transistor?
The 2N2222 is a common NPN bipolar junction transistor (BJT) used for general purpose low-power amplifying or switching applications. It is designed for low to medium current, low power, medium voltage, and can operate at moderately high speeds. It was originally made in the TO-18 metal can as shown in the picture.
What is difference between 2N2222 and BC547?
The 2N2222 has an emitter, base, and collector pinout, whereas the BC547 has a collector, base, and emitter pinout. The collector to base voltage at 2N2222 is 60 volts, whereas it is 50 volts at BC547, and the collector to emitter voltage is 30 volts at 2N2222 vs 45 volts at BC547.
Can I use BC548 instead of 2N2222?
The BC548 is more compactable than 2n2222 due to the package, 2n2222 has the metal package and BC548 have common plastic with the epoxy package. Other than some dissimilarities 2n2222 and BC548 transistors are equivalent to each other.
Why NPN is mostly used?
Which transistor is mostly used?
The MOSFET is by far the most widely used transistor for both digital circuits as well as analog circuits, accounting for 99.9% of all transistors in the world. The bipolar junction transistor (BJT) was previously the most commonly used transistor during the 1950s to 1960s.
What does PNP mean?
PnP
Acronym | Definition |
---|---|
PnP | Philippine National Police |
PnP | People’s National Party |
PnP | People’s National Party (Jamaica) |
PnP | Passauer Neue Presse (German newspaper) |
What does NPN and PNP stand for?
NPN stands for Negative, Positive, Negative. Also known as sinking. On an IO Module, an NPN input, when undriven is pulled down to be in a low state, GND ( or reference voltage level e.g. V-). PNP stands for Positive, Negative, Positive. Also known as sourcing.
What is the use of NPN and PNP?
NPN transistors are used as a sink to the current i.e., current flows to the Collector. It means the current points inwards. PNP transistors are used as a source to the current i.e., current flows out of the Collector. In the NPN transistor, electrons are important current carriers.
What is NPN resistor?
What NPN means?
Negative, Positive, Negative
NPN stands for Negative, Positive, Negative. Also known as sinking.
Can I use 2N2222 instead of 2N3904?
The 2N3904 or 2N2222 will suffice if you require less than 200mA. The 2N2222 is the one to choose if you require more than 200mA but not more than 1A. For most circuits, a 2N3904 would suffice, however, if you need more above 200mA, a 2N2222 should be used instead.
Is 2N2222 obsolete?
This product is no longer manufactured.
