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.

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.

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.

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.

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.

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.

What is bias and gain?

When the input signal is set to its minimum value, the “Bias” adjustment is set for the minimum power level (power to the load at 0 volts / 0 amps). When the input signal is set to its maximum value, the “Gain” adjustment is set for the maximum power level (power to the load at line voltage / line amperage).

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.

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.

Are 2N2222 and 2N2222A same?

The 2N2222A is the "improved" version of the 2N2222. You should be able to substitute the former for the latter in any circuit (but not necessarily vice versa). I would suspect that you wouldn't be able to find a supplier of the 2N2222 these days since the A version has been around for a long time.

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 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 BC547 transistor is 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 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.

How do I know if my Plc is NPN or PNP?

Power on the system and carefully measure the voltage between 0V and the black wire. If there is a voltage of +24V when the sensor is active, it is a PNP-type sensor. If there is a 0V reading on the multimeter when the sensor is active, it is most likely an NPN sensor.

Can I use PNP instead of NPN?

Generally, the PNP transistor can replace NPN transistors in most electronic circuits, the only difference is the polarities of the voltages, and the directions of the current flow. PNP transistors can also be used as switching devices and an example of a PNP transistor switch is shown below.
