2N3904 datasheet, 2N3904 pdf, datasheet, datas sheet, fiche technique, datasheets, fiches techniques, pdf, AUK Corp, Transistor de silicium de NPN (petite application générale de signal) The 2N3904 are a good inexpensive general purpose NPN transistor for low power amplification and switching and should be part of every parts bin. These can be very handy when you need to boost the output of a uC pin to drive something that it can not drive directly.

Power transistors typically can dissipate a watt or more of power, while small-signal ones dissipate less than a watt. The maximum dissipation for a 2N3904 is 350 mW (milliwatts), and so it is classified as small signal. The 2N3904 is a common NPN bipolar junction transistor used for general-purpose low-power amplifying or switching applications. [1] [2] [3] It is designed for low current and power , medium voltage , and can operate at moderately high speeds. hfe and other “h” parameters for this series of transistors. To obtain these curves, a high−gain and a low−gain unit were selected from the 2N4401 lines, and the same units were used to develop the correspondingly numbered curves on each graph. Figure 11.
