I've searched for a datasheet and found one from Promax-Johnton (who?) with "1W OUTPUT AMPLIFIER OF POTABLE RADIOS IN CLASS B PUSH-PULL OPERATION" which is worse than Chinese to me. My questions are: Is the 2N9013 a good replacement for my 2N3904? What additional considerations I need to be aware? Recommendations? 2N3904 datasheet, 2N3904 datasheets, 2N3904 pdf, 2N3904 circuit : ONSEMI - General Purpose Transistors(NPN Silicon) ,alldatasheet, datasheet, Datasheet search site for Electronic Components and Semiconductors, integrated circuits, diodes, triacs, and other semiconductors. 2N3904 General Purpose Transistors NPN TO-92 Page 1 31/05/05 V1.0 High Speed Switching Features: • NPN Silicon Planar Switching Transistors. • Fast switching devices exhibiting short turn-off and low saturation voltage characteristics.

Buy Transistor 2N3904 NPN General Purpose (bulk) ... Representative Datasheet, MFG may vary. You may also like: 2N3904RLRP. 2N2222A. 2N3906RLRP. BC547B. PN2222ABU ... Figure 2: 2N3904 circuit example - drawn in Scheme-it®. 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.
