The complementary PNP transistor is 2N3906. It is a 200 mA, 40 V, 625 mW transistor with a transition frequency of 300 MHz, with a minimum beta, or current gain, of 100 at a collector current of 10 mA.Įlectrically similar devices, such as the MMBT3904, are available in a variety of small through-hole and surface-mount packages, including TO-92, SOT-23, and SOT-223, with package-dependent thermal ratings from 625 milliwatts to 1 watt. 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 a low-cost device, widely available and sufficiently robust to be of use by experimenters and electronics hobbyists. The construction of the 2N3904 and 2N3906 in the 1960s represented a significant performance and cost improvement, with the plastic TO-92 case replacing metal cans. Both types were registered by Motorola Semiconductor in the mid-1960s.ĭevice packaging and specifications It is complementary to the 2N3906 PNP transistor. It is designed for low current and power, medium voltage, and can operate at moderately high speeds. The 2N3904 is a common NPN bipolar junction transistor used for general-purpose low-power amplifying or switching applications.
