What is BC547B transistor?

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. 250°C/W Junction to Ambient Thermal Resistance.

What does HFE mean in transistors?

hFE is an abbreviation, and it stands for “Hybrid parameter forward current gain, common emitter”, and is a measure of the DC gain of a junction transistor. So on a multimeter, it indicates a mode where the meter can measure (probably crudely), the HFE of a transistor.

Which transistor is equivalent to BC547?

BC547 Transistor Equivalent BC547 transistor can be used as an alternative to many transistors: BC548, BC549, BC636, BC639, 2N2222 TO-92, 2N2222 TO-18, 2N2369, 2N3055 and 2N3904 all are BC547 transistor equivalent.

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.

How do you know if a transistor is working?

Connect the base terminal of the transistor to the terminal marked positive (usually coloured red) on the multimeter. Connect the terminal marked negative or common (usually coloured black) to the collector and measure the resistance. It should read open circuit (there should be a deflection for a PNP transistor).

How do you read a BC547 transistor?

Features

2. Continuous Ic (collector current) = 100mA.
3. VBE (emitter-base voltage) = 6V.
4. IB (base current) = 5mA.
5. The polarity of the transistor is NPN.
6. The transition frequency is 300MHz.
7. It is obtainable in semiconductor package like-92.
8. Power dissipation is 625mW.

Why BC547 transistor is used?

BC547 Transistor Application 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 the 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.
