The NPN Bipolar Transistor is designed for use in linear and switching applications. The device is housed in the TO-92 package, which is designed for medium power applications.
The 2N3904 from Fairchild is a through hole, NPN general purpose transistor in TO-92 package which is designed for amplifier and switch application. The dynamic range of device extends to 100mA while operating as switch and it will be 100MHz for amplifier.Expand
