In this article, I would like to explain What is BC547 Transistor, where we can use it, and also the BC547 Datasheet, Applications of BC547, its Characteristics, and BC547 Pinout. All the Electronics circuit-based projects will be discussed on this website Circuits99.com.
What is BC547 Transistor
BC547 Transistor Working
BC547 transistor has minimum and maximum gain values are 110 to 800, it is denoted by (hFE). This gain value determines the amplification capacity of the transistor. The collector’s maximum current flow is 100mA. That is why we cannot connect more than 100mA consume load through this transistor. The base current (IB) is limited to 5mA.
The value of this resistor (RB) can be calculated using the below formulae.
RB = VBE / IB
Where the value of VBE should be 5V for BC547
Base current (IB depends on the Collector current (IC).
The value of IB should not exceed mA.
