2N3904 Transistor Explained / Description:

2N3904 is a widely used general purpose transistor. It is mostly used by electronic students and hobbyists in their projects, but it is also used in commercial electronic products. It can be used in wide variety of electronic applications for switching and amplification purposes. The maximum collector current of the transistor is 200mA therefore user can drive loads under 200mA in their electronic applications, Moreover 2N3904 also work good as an amplifier, the total device dissipation is 625 milliwatt due to which it can also be used for audio and RF signal amplification purposes.
