2N2907A Small Signal Switching Transistor PNP Silicon Features • MIL−PRF−19500/291 Qualified • Available as JAN, JANTX, and JANTXV MAXIMUM RATINGS Rating Symbol Value Unit Collector−Emitter Voltage VCEO −60 Vdc Collector−Base Voltage VCBO −60 Vdc Emitter−Base Voltage VEBO −5.0 Vdc Collector Current − Continuous IC −600 mAdc Since the 2N3904 is an NPN transistor, that means the base needs positive biasing (appropriate voltage levels and resistance) to turn on the collector emitter junction for proper current flow. Use of a load resistor (R1 above) is also important so there is not too much current being driven through the LED and transistor. ON Semiconductor offers a comprehensive portfolio of innovative energy efficient power and signal management, logic, discrete, and custom semiconductor solutions.
