The 2N3904 is a common NPN bipolar junction transistor used for general-purpose low-power amplifying or switching applications. It is designed for low current and power, medium voltage, and can operate at moderately high speeds. 2n3904s revision no : 4 c 0 collector current i (ma) collector current i (ma) 0 c 0 base-emitter voltage v (v)be i - vc be 10 dc current gain h fe 0.1 0.3 1 3 collector current i (ma)c 0 collector-emitter voltage v (v)ce i - vc ce h - i collector current i (ma)c collector-emitter saturation ce(sat) v - i

Although this works fine, I'm a bit concerned about what I've read on the data sheet for the 2N3904. It states that the Base-Emitter Saturation Voltage has the following specs: Ic = 10mA Ib = 1.0mA Ic = 50mA Ib = 5.0mA. I'm having a hard time understanding what that means exactly. 2N3904 Datasheet : SMALL SIGNAL NPN TRANSISTOR, 2N3904 PDF VIEW Download STMicroelectronics, 2N3904 2 page Datasheet PDF, Pinouts, Data Sheet, Equivalent, Schematic, Cross reference, Obsolete, Circuits 2N3904 MMBT3904 PZT3904 C C E E C C TO-92 B B SOT-23 B E SOT-223 Mark: 1A NPN General Purpose Amplifier This device is designed as a general purpose amplifier and switch.
