This transistor is also available in the SOT-23 case with the type designation MMBT3904.On special request, this transistor is also manufactured in the pin configuration TO-18.As complementary type, the PNP transistor 2N3906 is recommended.NPN Silicon Epitaxial Planar Transistor for switching and amplifier applications.2n3903 2n3904.pdf Size:212K motorola MOTOROLAOrder this. The pin outs of the transistor 2N3904 are given in the following diagram.TO-226AA (TO-92) 2N3904 Small Signal Transistor (NPN) New Product min. The above data is quite sufficient and adequate for any electronic hobbyist for understanding the transistor 2N3904 safely and correctly.The minimum amount of voltage required to trigger the base of the device is 0.65 volts, its also called the case/emitter saturation voltage. The 2N3904 is rated for a maximum of 40V between Collector and Emitter, and 200mA Collector current.The minimum amount of voltage required for activating the collector is 0.2 volts, its also known as the collector-emitter saturation voltage.The hFE or the forward current gain of the device is between 100 to 300.Similarly the minimum amount of current required to keep the collector load switched is also 50nA.It has a maximum Collector-Emitter voltage of 40V, Collector-Base voltage of 60V, and Base-Emitter voltage of 6V. Minimum current required for keeping the base of the transistor activated is 50nA. 2N3904 is a general purpose NPN transistor.The maximum base to emitter breakdown voltage is 6 volts. ![]()
