1996. 1. 28 1/3 semiconductor technical data kn3904 epitaxial planar npn transistor revision no : 0 general purpose application. switching application. Since the 2N3904 is an NPN transistor, that means the base needs positive biasing (appropriate voltage levels and resistance) to turn on the collector emitter junction for proper current flow. Use of a load resistor (R1 above) is also important so there is not too much current being driven through the LED and transistor. 2N3904 NPN Small Signal Transistor Epitaxial Planar Die Construction Available in both Through-Hole and Surface Mount Packages Ideal for Switching and Amplifier Applications Complementary PNP Type Available (2N3906).
