of the production of semiconductor transistors, generally made of silicon material is the ''NPN'' type, and the production of germanium material is ''PNP'' type. Arrow points to the emitter circuit base is ''PNP'' type, the down arrow on the emitter is ''NPN'' type. Of course, not only the amplification transistor, as well as oscillation, switches and so on. About not through the Internet all of a sudden, you want to learn more about, we must refer to some of the books, such as semiconductor knowledge on the line, then go deep further study will understand more. Thank you for your concern, but also want you to progress more quickly!
