Transistor npn 2n2222 datasheet

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 It was originally made in the TO-18 metal can as shown in the picture.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 equivalent of 2N2222?

2N2222 Equivalents 2N3904, BC547, BC548, and 2N3906 are 2N2222 comparable transistors.

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.

What is the difference between NPN transistor bcn42 and 2N2222?

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.

Where is 2N2222A transistor used?

The 2N2222A transistor is a common NPN BJT & it is mainly used in the applications of switching & amplifying with less power. This transistor is mainly designed for low power, low to medium current, medium voltage & works at fairly high speeds.

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 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.

Can a 2N2222 replace 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.

Can I use C945 instead of 2N2222?

As far as specs are concerned the C945 has more gain, Hfe, than the 2N2222, but for most applications yes you could use C945 in place of the 2N2222. One issue though is C945 has different pin out than the 2N2222. The 2N2222 base has pin out of emitter-base-collector (base is center pin).

How does a 2N2222 transistor work?

Working of 2N2222 As I have mentioned before, it's a current controlled transistor. So, a small current at the base terminal is used to drive high current between the other two terminals. It is used for switching purposes because of its fast response time.

Can I use 2N3904 instead of 2N2222?

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.

Are NPN transistors interchangeable?

An NPN has the arrow pointing AWAY from the base. NPN and PNP transistors are NOT interchangeable! A circuit that is designed for one type will NOT work with the other type. There are two differences between NPNs and PNPs that will prevent the wrong type from working in this circuit.

What are the types of NPN transistor?

NPN transistors are formed when a p-type semiconductor material (either Silicon or Germanium) is fused between two n-type semiconductor materials, as we already know. The NPN transistor is made up of a number of different components. It is divided into three sections: emitter, base, and collector.

Is NPN and PNP transistor same?

There are numerous difference between NPN and PNP transistors, even though both are bipolar junction transistors. There are applications which makes transistors as a device- switch and amplifier. In a PNP transistor, the majority charge carriers are holes while in NPN the majority charge carriers are electrons.

What are the 3 function of transistors?

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

What are the 2 purposes of a transistor?

Transistors are also used for low-frequency, high-power applications, such as power-supply inverters that convert alternating current into direct current. Additionally, transistors are used in high-frequency applications, such as the oscillator circuits used to generate radio signals.

Where is NPN used?

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.

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.

Which transistor is the fastest?

The world's fastest silicon transistor has reached the incredible speed of 798 GHz. This is 200 GHz faster than the previous record. The transistor was developed in a collaboration between German and American scientists in a project that aims to approach THz speeds at room temperature.
