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 transistor handle?

It’s a current controlled transistor. It has a Collector current of 800 mA. Power Dissipation of 2N2222 is 500mW. It can operate between -65 C to 200 C temperature.

What is the frequency limit of transistor?

GaAsFETs can be used from below 1 GHz to beyond 18 GHz whereas the BJTs can operate up to about 10 GHz. Research on high electron mobility transistors (HEMT) and GaAs heterojunction bipolar transistors (HBT) in recent years has promised the potential application of ‘transistors’ at millimetre-wave frequencies.

What is the beta value of 2N2222 transistor?

In this experiment we measure the constant β ≡ Ic/Ib for a 2N2222 transistor. We show that β is in fact constant in the linear regime and equal to approximately 190. In addition, we show that the linear regime is realized for base currents of Ib < 50 μ A and that in this regime the voltage hierarchy is satisfied.

What does 2N2222 transistor do?

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.

What electronics use 2N2222 transistor?

2N2222 NPN transistor has been commonly used for switching and very high frequency(VHF) amplifier applications. It is made of silicon material and specially designed for low voltage, low to medium current and low power amplifier applications.

Can I use 2N3904 instead of 2N2222?

Usually a 2N3904 will suffice for most circuits, but if you need more than 200mA, then you should use a 2N2222 instead….2N3904 vs 2N2222.

Can we use BC547 instead of 2N2222?

You can update the circuit at anytime, you can replace the 2n2222 NPN transistors with the BC547 and it will have no negative effect on the project.

Which transistor can be used in place of 2N2222?

The 2N2907 is an equally popular PNP transistor complementary to the 2N2222. The 2N3904 is an NPN transistor that can only switch one-third the current of the 2N2222 but has otherwise similar characteristics.

What is the difference between 2N2222 and 2n2222A?

The 2n2222A is a slight bit better in terms of Vceo, Vcbo, Vebo. But if you are not planning on stressing the part (higher voltages, etc) both will work well, especially for simple switching and logic circuits. The 2n2222 part is the older style part which might be the reason they are being offered at a low price.

What does 2n2222 transistor do?

What is the power dissipation of a 2N2222 transistor?
