2n2222 datasheet

What are 2N2222 and 2N2222A Transistors? Both transistors are from the same family but the 2N2222A has higher Maximum absolute ratings than 2N2222. The Collector to Base, Emitter to Base, and Collector to Emitter voltage ratings of 2N2222 and 2N2222A are 60V, 30V, 5V, and 75V, 40V, 6V respectively.

What is 2N2222 used for?

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 It was originally made in the TO-18 metal can as shown in the picture.

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.

What electronics use 2N2222 transistor?

The NPN transistor like 2N2222 is most frequently used for VHF (very high frequency) amplifier & switching 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.

Can I use 2N2222 instead of 2N2222A?

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.

How can I use 2N2222 as a switch?

Below by flowing a small current through the base. As you can see as ib. These two then join and

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).

What is the difference between 2N2222 and 2n3904?

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.

What is the most powerful transistor?

As of 2022, the highest transistor count GPU is Nvidia's H100, built on TSMC's N4 process and totalling 80 billion MOSFETs.

Can I use BC548 instead of 2N2222?

They are the same and are used interchangeably most of the time. 2N2222 is a metallic package TO-18 and PN2222 is a plastic package TO-92, you can refer to the datasheet of them. Can I use BC548 instead of BC547? NO, BC547 is an NPN and BC548 is a PNP transistor both the transistors are not substituted for each other.

What is the cost of 2N2222 transistor?

₹55.00 FREE Delivery.

What is the most used transistor?

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.

Which transistor is used in Tesla coil?

Tesla Coil Raw Material Transistor 2222, Resistance 22k Full Kit.

What is the smallest transistor in the world?

Now, by using atomically thin materials, scientists in China have created a transistor with a record-breaking gate length of just roughly one-third of a nanometer wide, only as thick as a single layer of carbon atoms, shedding light on how much smaller—if at all—transistors can possibly get.

What is the fastest transistor?

Feng and Hafez developed a transistor less than half a millionth of a metre long, with a maximum operating speed of 604 GHz, meaning it can carry out 604 billion operations every second.

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.

What is the fastest electronic switch?

Detailed Solution. Amongst BJT, MOSFET, JEFT and Triode, MOSFET is the fastest switching device because of its quickest response.

Is PN2222 and 2N2222 the same?

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

Why use a transistor instead of a switch?

Transistors: Speed and Simplicity Transistors allow current to flow between the collector and emitter, as opposed to an on/off switch. They use no moving parts.
