Bc547 equivalent

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.

Is BC547 a PNP?

BC547, BC557 series devices are silicon NPN - PNP small signal transistors, manufactured by the epitaxial planar process, designed for general purpose amplifier ,switching and AF amplifier applications.

Can I use BC548 instead of BC547?

You will be fine with BC548, BC547 or 2N3904 your application is not demanding. The history of this comes from the original metal can NPN silicon devices that were called BC107, BC108 and BC109. These numbers are in ascending gain and descending breakdown voltage.

Is BC547 and BC548 same?

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 2N3904 instead of BC547?

The collector current of 2N3904 is 200mA and BC547 is 100mA therefore if the load you are driving with the 2N3904 is under 100mA then you can replace it with BC547 but if the load is above 100mA then you can not use BC547 instead of 2N3904.

Why is BC547 used?

BC547 is usually used for current amplifier, quick switching and pulse-width modulation (PWM). Therefore, if you need to control the speed of a motor or actuator in some of your projects, you can simply use this transistor to achieve it.

Can I use any transistor for amplifier?

You can also use other types of transistors, like JFETs or MOSFETs. Those would require a different circuit topology to utilize properly, but can be used to make a good amp too.

Can I use S8050 instead of BC547?

The BC547 is categorized as "designed for use as general purpose amplifiers and switches requiring collector currents to 300 mA." The S8050 is categorized as "a low voltage high current small signal NPN transistor, designed for Class B push-pull audio amplifier and general purpose applications."

What happens if the transistor is changed from BC107 To BC547?

It looks like the BC547 is a modern replacement for the BC107. They are packaged differently but otherwise look very similar in terms of electrical characteristics. They seem to have the same breakdown voltage; the BC547 seems to have slightly better cutoff frequency. The current gain has a very similar range.

Why 2N2222 transistor is used?

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.

Is BC547 same as 2N3904?

The equivalent for 2N3904: BC548, BC547, BC636, BC639, 2N2222A, 2N2222, 2N2369, 2N3055, 2N3906, 2SC5200 are equivalent to 2N3904.

Is BC547 an amplifier?

BC547 Double Transistor Audio Amplifier.

Can I use BC557 instead of BC547?

Yes. You can use BC557 in place of BC547. And similarly, you could use BC558 in place of BC557.

Can I replace PNP with NPN transistor?

NPN transistor is made by sandwiching p-type between two n-type semiconductors by a process called doping. Similarly, for that of PNP transistor. Thus, once made cannot be altered. So, we cannot change an NPN into a PNP transistor.

Can I use PNP instead of NPN?

Generally, the PNP transistor can replace NPN transistors in most electronic circuits, the only difference is the polarities of the voltages, and the directions of the current flow. PNP transistors can also be used as switching devices and an example of a PNP transistor switch is shown below.

How does a BC547 work?

BC547 Transistor Working At the border of the P and N, a depletion region is created, which blocks the flow of charge carriers from one region to another. When the input voltage is applied at its Base terminal, some amount of current starts to flow from the base to the emitter and controls the current at the collector.

How do I use BC547 as a switch?

Useful Steps

Place Transistor on a breadboard.
Connect Emitter to the ground of the battery.
Add LED & 330 Ohm Resistor to Collector of BC547.
Connect 1k Resistor and Switch to Base of transistor.
Power up the circuit with 9V Battery.

What is the most used transistor?

The MOSFET is by far the most widely used transistor for both digital circuits as well as analog circuits, accounting for 99.9% of all transistors in the world. The bipolar junction transistor (BJT) was previously the most commonly used transistor during the 1950s to 1960s.

Which transistor is best for audio amplifier?

#1. TIP 3055 NPN and TIP 2955 PNP Complementary Pair Transistors. These transistors are widely used in old design class AB-type amplifiers. The maximum power dissipation of the Transistor is 90-Watts.
