Common questions

How do I use BC548?

How do I use BC548?

BC548 is used in the following applications:

  1. Used in Darlington pairs to amplify weak signals.
  2. It can be employed in sensor circuits.
  3. Driving loads under 500mA.
  4. Used in audio amplification.
  5. Used in audio Amplifier Stages.

Where is 2N2222 transistor 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.

What is the use of BC547 transistor?

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.

What is BC557 transistor?

BC557 is a general-purpose transistor, used like an amplifier or a switch in electronic circuits. Its hFE ratings of this transistor range from 125 to 800 to make the transistor ideal by using like an amplifier within electronic circuits like audio signal amplification.

Can I use BC548 instead of BC547?

NO, BC547 is an NPN and BC548 is a PNP transistor both the transistors are not substitute to each other.

What number transistor is a PNP?

PNP Transistors

Manufacturer Part Number Description Transistor Type
STN9260 TRANS PNP 600V 0.5A SOT-223 PNP
2STR2230 TRANS PNP 30V 1.5A SOT-23 PNP
STR2550 TRANS PNP 500V 0.5A SOT-23 PNP

What is the beta 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.

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 difference between BC547 and BC557?

BC557 is PNP, BC547 is NPN to see what is this transistor reconstruct circuit from existing PCB on paper, then you will know.

What is BC547B transistor?

The BC547B is a NPN Transistor, suitable for use in driver and output stages of audio amplifier, low noise input stages of tape recorders, Hi-Fi amplifiers and signal processing circuits of television receivers.
