2N3904 NPN General Purpose Transistor 40V 200mA – TO-92 Package 2N3904 NPN General Purpose Transistor 40V 200mA – TO-92 Package 2N3904 is a semiconductor device used to amplify or switch electronic signals and electrical power. It is composed of semiconductor material usually with at least three terminals for connection to an external circuit. A voltage or current applied to one pair of the transistor’s terminals controls the current through another pair of terminals. Because the controlled (output) power can be higher than the controlling (input) power, a transistor can amplify a signal. Today, some transistors are packaged individually, but many more are found embedded in integrated circuits.
