What is the beta value of 2N2222?
What is the beta value of 2N2222?
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 is beta in NPN transistor?
The beta (β) of a transistor, or transistor current gain, is the ratio of the transistor’s collector current (Ic) to its base current (Ib), as shown in Equation 1. β = Ic/Ib. (1) The β value is fixed for a given transistor and operating condition.

What is 2N2222 NPN transistor?
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 is the difference between 2N2222 and 2N2222A?
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.
How does a 2N2222A transistor work?
2N2222A is a NPN transistor hence the collector and emitter will be left open (Reverse biased) when the base pin is held at ground and will be closed (Forward biased) when a signal is provided to base pin. 2N2222A has a gain value of 110 to 800, this value determines the amplification capacity of the transistor.
How do I calculate beta?
Beta could be calculated by first dividing the security’s standard deviation of returns by the benchmark’s standard deviation of returns. The resulting value is multiplied by the correlation of the security’s returns and the benchmark’s returns.
What is the general value of beta?
Typically, β has a value between 20 and 200 for most general purpose transistors.
How many watts can a 2N2222 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.
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.
Which transistor can be used in place of 2N2222?
Both the BC547 and 2N2222 are bipolar NPN transistors. 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.
How much current can a 2N2222 transistor handle?
