Hello everyone! I hope you will be absolutely fine and having fun. Today, I am going to give an Introduction to 2N3904. It is basically an NPN transistor made up of silicon material. It acts as a general purpose amplifier and switch. You should also have a look at Introduction to 2N2222, which is also an NPN transistor and considered as 2N3904 equivalent.
It is mostly used for lower power amplifiers and switching applications. Its major functional area is enclosed in TO-92 package. Its a silicon NPN general purpose bipolar junction (BJT) transistor designed for switching purpose as well as for an amplifier. Its can bear lower amount of current, lower power and medium voltage levels. It is most commonly used BJT due to its smaller size, wide avai ...
