What is BC547?
This is a maximum voltage rating of 45V and a maximum current rating of 100mA, NPN general-purpose transistors in small plastic packages.
The BC547 is a general-purpose NPN bipolar junction transistor (BJT) that is commonly used in electronic circuits due to its low cost and wide availability.
While the BC547 is a great transistor for many applications, there are also other parts available that have different characteristics and may be better suited for specific circuits. For example, the BC548 is a similar transistor to the BC547, but it has a higher voltage rating of 30V. The BC549 is another similar transistor, but it has a lower noise figure and higher gain than the BC547. The 2N2222 and 2N3904 are also commonly used transistors that can be used as replacements for the BC547 in many circuits.
