## What is the beta value of 2N2222?

approximately 190
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 for A 2N3904 transistor?

For your transistor, the ubiquitous 2N3904, Fairchild’s datasheet quotes a minimum beta of 100 and a typical of 300 at 10mA collector current and 1V from collector to emitter.

What is beta value 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. The β value is fixed for a given transistor and operating condition.

### What is β of a transistor?

β (beta) of a transistor is the gain or amplification factor of a transistor. It is the factor by which current is amplified in the circuit. So if a transistor has a β of 100, the base current that goes into it is amplified by 100.

### What is the beta of a 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. The β value is fixed for a given transistor and operating condition. Figure 1 shows a simplified amplifier input stage using bipolar transistors.

What is the pin configuration of 2N2222 NPN transistor?

Pin Configuration of 2N2222 NPN Transistor: This 2N2222 NPN transistor has three pins emitter, base, and collector. These pins are used in the circuit for turning on or off the transistor. Its pin configuration diagram is shown here according to the datasheet: The emitter pin is used for draining out the whole transistor current.

## What is 2N2222A transistor used for?

2N2222A (TO-18 package) with the emitter, base and collector identified as E, B, and C respectively. The 2N2222 is a common NPN bipolar junction transistor (BJT) used for general purpose low-power amplifying or switching applications.

## What is the difference between 2N2222 and 2N2907?

2N2222. The BC548 is a low voltage, low current, general-purpose switching transistor in a TO-92 package. 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 BC547 and 2N2222A transistors?

But there are two important features that distinguish both. 2N2222A can allow collector current upto 800mA and also has power dissipation of 652mW which can be used to drive larger loads than compared with BC547. So if you looking for an NPN transistor that could switch loads of higher current, then 2N2222A might the right choice for your project.
