![]() ![]() It is designed for low and, medium, and can operate at moderately high speeds. The type was registered by in the mid-1960s, together with the complementary PNP type, and represented a significant performance/cost improvement, with the plastic TO-92 case replacing metal cans. The 2N3904 is a common used for general-purpose low-power or switching applications. ![]() ![]() The pinout from left to right is: Emitter, Base, Collector. ![]() Wikimedia Commons has media related to.A 2N3904 made. McGraw-Hill Professional.ĭatasheet Reference. 123 robotics experiments for the evil genius. Circuitbuilding do-it-yourself for Dummies. Whereas the 2N2222 is optimized to reach its highest gain at currents of around 150 mA, the 2N3904 is optimized for currents of around 10 mA. Nevertheless, in many applications such as variable-frequency oscillators, where lower currents are used to minimize thermal heating and consequent thermal drift of the fundamental frequency, the greater current capacity of the 2N2222 gives it no advantage. The higher-power is a very similar NPN transistor that can safely switch three times as much current as the 2N3904. Related parts Electrically similar devices, such as the MMBT3904, are available in a variety of small through-hole and surface-mount packages, including, and SOT-223, with package-dependent thermal ratings from 625 to 1.The 2N3904 is used very frequently in hobby electronics projects, including home-made, code-practice oscillators and as an interfacing device for. It is used in a variety of analog amplification and switching applications. It is a 200, 40, 625 transistor with a of 300, with a minimal, or current gain, of 100 at a collector current of 10.Įgr removal keygen torrent. Some manufacturers mark 'EBC' on the molded part, but all are required to have those connections for a part which is a '2N3904'. When looking at the flat side with the leads pointed downward, the three wires emerging from the bottom are connected to, from left to right, the emitter, the base and the collector. This transistor is low-cost, widely available and sufficiently robust to be of use by experimenters and electronics hobbyists. ![]()
