BC547 Transistor

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.

Transistors are small devices which is control the flow of electricity in circuits. They are used to amplify signals and control the flow of electricity. Transistors come in many different shapes and sizes, and a variety of electronic devices. The first transistor was discovered in 1947, and today billions of transistors are used in electronic devices and circuits every year.

What is BC547 Transistor

BC547 Transistor Working

BC547 transistor has minimum and maximum gain values are 110 to 800, it is denoted by (h_FE). 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 (I_B) is limited to 5mA.

In most cases, the BC547 transistor is used as a switch and it is operated in the saturation and cut-off region. When the transistor acts as an open switch during forwarding Bias and in Reverse Bias, it acts as a Closed switch. Here the maximum biasing current does not exceed 5mA in that case the transistor will damage.

The value of this resistor (R_B) can be calculated using the below formulae.

R_B= V_BE / I_B

Where the value of V_BE should be 5V for BC547

Base current (I_B depends on the Collector current (I_C).

The value of I_Bshould not exceed mA.
