Some of the text within the PDF file :

The 2N3904 is NPN switching transistor. This transistor is a widely used bipolar junction transistor (BJT) that belongs to the NPN (Negative-Positive-Negative) type. It is commonly employed in electronic circuits for amplification and switching purposes. The 2N3904 is a small-signal transistor, meaning it is designed to handle low power and small voltage levels.
