Which transistor can be used in place of 2N3904?

The 2N3904 (NPN) and 2N3906 (PNP) are complementary transistor pairs. These transistors are available in package styles TO-92, SOT23, SOT223 with different prefixes.

Can I use 2N2222 instead of 2N3904?

since the 2N3904 and 2N2222 have the same maximum VCEO voltage, there is no difference in this regard. A 2N2222 can handle up to 5 times that amount of current, as it can handle up to 1A (amps) of current flow from emitter to collector to power a load.

What is the beta of 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.

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.

Can I 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.

What is the difference between BC547 and BC548?

This group of NPN transistors share many specifications and characteristic curves, but differ in voltage ratings – the BC546 and BC547 are essentially the same as the BC548 but selected with higher breakdown voltages, while the BC549 is a low noise version, and the BC550 is both high-voltage and low-noise.

Can I use BC547 instead of 2N2222?

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.

Is beta constant for a transistor?

Hint: The constant α of a transistor is the ratio of the collector current to the emitter current while the constant β of the transistor is the ratio of the collector current to the base current.

What type NPN or PNP is a 547 transistor?

Since the power between the emitter and collector can be higher than the base, transistors are often used as amplifiers. The BC547 is a NPN transistor meaning when power is applied to the base (control pin) it will flow from the collector to the emitter.

What can we use instead of transistor?

Relays: Normally closed relays are all you need to make any logic gate. Normally open relays are also useful. Mag-amps: Magnetic amplifiers could be used to make logic gates similarly to transistor-transistor logic.

What is the difference between NPN transistor bcn42 and 2N2222?

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 kind of transistor is 2N3904 used for?

The 2N3904 is an extremely popular NPN transistor that is used as a simple electronic switch or amplifier that can handle 200 mA (absolute maximum) and frequencies as high as 100 MHz when used as an amplifier.

What do you need to know about 3904 transistors?

Here is a link that shows various package sizes for 3904 transistors. Figure 2: 2N3904 circuit example – drawn in Scheme-it®. Since the 2N3904 is an NPN transistor, that means the base needs positive biasing (appropriate voltage levels and resistance) to turn on the collector emitter junction for proper current flow.

What is the Digi key part number 2N3904?

Figure 1: An illustration of the pin out of a standard TO-92 package for Digi-Key part number 2N3904FS-ND: E = Emitter, B = Base, C = Collector. Figure 2 shows a circuit example which turns on the collector emitter junction by energizing the base or biasing the transistor to turn it on by bringing 5 volts to the base via a slide switch.
