2n3904 npn transistors

The 2n2222 transistor's main advantage over other similar transistor types is its ability to handle high currents. 2n3904 has a collector current of 200mA, while 2n2222 has a collector current of close to 1ampere, allowing 2n2222 to handle high-value loads like 2n3904.

Is BC547 same as 2N3904?

The equivalent for 2N3904: BC548, BC547, BC636, BC639, 2N2222A, 2N2222, 2N2369, 2N3055, 2N3906, 2SC5200 are equivalent to 2N3904.

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 the difference between 2N3904 and 2N4401?

2N3904 and 2N4401 appear to be very comparable parts in all specs. 2N4401 has a higher current rating, but otherwise they look to be about the same in price and everything else. Obviously it's difficult to give a 100% universal answer since both parts are made by multiple manufacturers.

Is 2N3904 NPN or PNP?

Since the 2N3904 is an NPN transistor, that means the base needs positive biasing (appropriate voltage levels and resistance) to turn on the collector emitter junction for proper current flow.

Which transistor can be used in place of 2N3904?

Given below is the list of popular transistors which can be used as a replacement for 2N3904: BC537, BC538, 2N4401, and P2N2222A. BC547 and BC548 are functionally equivalent transistors.

How does 2N3904 NPN transistor work?

2N3904 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. 2N3904 has a gain value of 300; this value determines the amplification capacity of the transistor.

Is 2N3906 NPN or PNP?

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 2N3906 an NPN?

2N3906 Transistor is a popular PNP bipolar junction transistor used in low power and current, medium voltage applications. It is widely used for low power amplification and switching. 2N3906 is complementary to 2N3904 NPN bipolar junction transistor.

What is the early voltage of 2N3904?

Emitter-Base Voltage Vebo of 2N3904 is 6V.

What is the hFE of 2N3904?

A 2N3904 has an hFE of between about 25 and 400, depending on the operating conditions. It says so plainly in the data sheet characteristics charts. (The gain of any transistor will vary widely depending on the exact circuit conditions).

Is PN2222 same as 2N2222?

PN2222 and 2N2222 are both NPN bipolar junction transistors, and they are interchangeable under most circumstances.

How do I know if my NPN is PNP?

The schematic symbols for NPN and PNP transistors are extremely similar. The sole distinction is the orientation of the arrow on the emitter. It points outward in an NPN (on the left) and inward in a PNP (on the right).

Can I use any NPN transistor?

You can use any NPN type transistor (for example 2N3904, BC547, BC548, BC549 etc.) These are basic circuits, so they can be improved (with diodes for reverse voltage protection, for example), or can be simplified (XOR, XNOR gates), but for start we will stick with these basic circuits.

Can I use a PNP sensor as NPN?

For example, you can use NPN sensors with an NPN Input card or “sourcing type” Input card. However, you can't use PNP sensors with an NPN input card.

What type is NPN transistor?

The NPN transistor consists of two n-type semiconductors that sandwich a p-type semiconductor. Here, electrons are the majority charge carriers, while holes are the minority charge carriers. The NPN transistor is represented, as shown below.

Can I use 2N3904 instead of BC548?

EDIT: The 548 is 100mA, 30V. The 3904 is 200mA, 40V. So compatible within the specs.

Are all 2N3904 the same?

Both the 2N3904 and 2N2222 are identical in terms of handling collector-to-emitter voltages, and both can handle voltages of up to 40V. In simple terms, this effectively means that 40V is the maximum amount of voltage that the transistor can handle minus the voltage drop across the load connected to the collector.

What is a NPN transistor used for?

NPN transistors are used in amplifying circuit applications. NPN transistors are used in the Darlington pair circuits for amplifying weak signals. NPN transistors are used in applications we need sinking current. NPN transistors are used in some classic amplifier circuits, the same as 'push-pull' amplifier circuits.

Why NPN is mostly used?

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.
