What is the use of transistor 2N2222A?

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.

What is the difference between 2N3904 and 2N3906?

The 2N3906 is specified by a collector current of 200 mA, collector-base and collector-emitter voltages of 40 V, for power dissipation of 300 mW. The complementary NPN transistor to the 2N3906 is the 2N3904. Both types were registered by Motorola Semiconductor in the mid-1960s.

What is 2n222a 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. It was originally made in the TO-18 metal can as shown in the picture.

What is difference between BC547 and 2N2222 transistor?

The 2N2222A transistor is very much similar to the commonly used NPN transistor BC547. 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.

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 is the beta value of q2n2222?

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 the difference between PNP and NPN transistors?

An NPN transistor has a piece of P-type silicon (the base) sandwiched between two pieces of N-type (the collector and emitter). In a PNP transistor, the type of the layers are reversed. NPN and PNP transistors have very similar schematic symbols. The only difference is the direction of the arrow on the emitter.

What is the difference between 2N3904 and 2N4401?

2N3904 and 2N4401 appear to be very comparable parts in all specs. 2N4401 has a higher current rating, but otherwise they look to be about the same in price and everything else. Obviously it’s difficult to give a 100\% universal answer since both parts are made by multiple manufacturers.

How can a transistor be used as a switch?

With a zero signal applied to the Base of the transistor it turns “OFF” acting like an open switch and zero collector current flows. With a positive signal applied to the Base of the transistor it turns “ON” acting like a closed switch and maximum circuit current flows through the device.

Which is the best NPN transistor?

Best Transistors: BJTs

• #1 NPN – 2N3904. You can find most often NPN Transistors in low-side switch circuits.
• #2 PNP – 2N3906. For high-side switch circuits, you need a PNP style BJT.

What is 2N3906 PNP transistor used for?

2N3906 PNP Transistor 2N3906 is a special purpose transistor that has been generally used for low current medium voltage and low power switching as well as amplification, but it is most suitable for high-speed switching. In the market, it is available in the plastic body and TO-92 dip package.

What is the difference between 2N3904 and 2N2222A?

It supports the current up to 100mA when acts as a switch and It supports the frequency up to 100MHz while acting as an amplifier. 2N2222A is also an NPN transistor and is quite similar to 2N3904. 2N3904 is NPN Bipolar Junction Transistor designed for switching purposes at 100mA and as an amplifier at 100MHz frequency.

What is the working principle of 2n2n3906?

2N3906 is a PNP (positive negative-positive) transistor therefore current flows from emitter to collector. It consists of three pins emitter, base, and collector and these pins are used for a different configuration. Its operating voltage range is -40V dc and pinout configuration with schematic symbol is shown in figure 1,
