2n4401 datasheet

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.

What is a 2N4401?

The 2N4401 from Multicomp Pro is a through hole, NPN low power, silicon planar epitaxial transistors in TO-92 metal can package. This device is used for general purpose switching applications. Collector emitter voltage (Vce) of 40V. Continuous collector current (Ic) of 600mA. Power dissipation of 625mW.

Which transistor is equivalent to BC547?

BC547 Equivalents The BC series, such as BC549 and BC639, are the finest recommendations for the BC547 transistor equivalent, followed by the 2N2222 transistor. BC636 replaces BC547, 2N2369, 2N3055, 2N3904, 2N3906, and 2SC5200 in the PNP.

What is transistor gain?

A transistor can use a small signal applied between one pair of its terminals to control a much larger signal at another pair of terminals. This property is called gain. It can produce a stronger output signal, a voltage or current, which is proportional to a weaker input signal and thus, it can act as an amplifier.

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.

Can I use BC547 instead of 2N3904?

The collector current of 2N3904 is 200mA and BC547 is 100mA therefore if the load you are driving with the 2N3904 is under 100mA then you can replace it with BC547 but if the load is above 100mA then you can not use BC547 instead of 2N3904.

Why is BC547 used?

BC547 is usually used for current amplifier, quick switching and pulse-width modulation (PWM). Therefore, if you need to control the speed of a motor or actuator in some of your projects, you can simply use this transistor to achieve it.

Can I replace PNP with NPN transistor?

NPN transistor is made by sandwiching p-type between two n-type semiconductors by a process called doping. Similarly, for that of PNP transistor. Thus, once made cannot be altered. So, we cannot change an NPN into a PNP transistor.

Which transistor is best for switching?

Both PNP and NPN transistors can be utilized as switches. A basic terminal transistor can be handled differently from a signal amplifier by biasing both NPN and PNP bipolar transistors by an “ON / OFF” static switch. One of the main uses of the transistor to transform a DC signal “On” or “OFF” is solid-state switches.

Why dB is used in gain?

It allows us to denote, both very small as well as very large quantities of linear, scale by considerably small figures. For example, voltage gain of 0.0000001 can be represented as -140 dB and voltage gain of 1,00,000 can be represented as 100 dB.

How is dB gain calculated?

DB Gain Calculator

Formula. dB = 10log10 (P2/P1)
Final Power (watts) (P1)
Initial Power (watts) (P2)

What is DC and AC gain?

DC voltage gain (also called steady-state voltage gain) is the ratio: outputvoltageinputvoltage for a direct voltage input. AC voltage gain is the same formula, but for unbiased sinusoidal input and output voltages. Cite.

How much voltage can a 2N2222 handle?

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.

How much current can a 2N2222 handle?

Typically, a 2N2222 transistor is able to switch 800 mA of load current through it, which may be considered quite high compared to the miniature size owned by these devices. High current switching capability also makes this device ideally suited for linear amplifier applications.

How fast can a 2N2222 switch?

The 2N2222 has a combined rise-time, fall-time, and storage-time of 310ns, thus the maximum switching frequency is about 3MHz so it's not appropriate for this application.

Why 2N2222 transistor is used?

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.

Which transistor is better NPN or PNP?

The mobility of electrons is better than the mobility of holes. Mobility of electrons is more than hole, so as a result n-p-n transistors are faster than p-n-p that's why they are preferred.

Is NPN better than PNP?

NPN Transistor Applications This presents a huge advantage in high-speed switching and amplifier circuits applications. Adding on to this advantage is the fact that NPN transistors are also easier, and thus cheaper, to manufacture than PNP transistors.

What are the 3 function of transistors?

transistor, semiconductor device for amplifying, controlling, and generating electrical signals.

Why NPN transistor is mostly used?

Generally the NPN transistor is the most used type of bipolar transistors because the mobility of electrons is higher than the mobility of holes. The NPN transistor has three terminals – emitter, base and collector. The NPN transistor is mostly used for amplifying and switching the signals.
