What's the difference between 2N3904 and 2N4401 . And the information I find from internet, the 2N3904 is a common NPN bipolar junction transistor used for general-purpose low-power amplifying or switching applications. The type was registered by Motorola Semiconductor in the mid-1960s, together with the complementary PNP type 2N3906, and represented a significant performance/cost improvement, 2n3904 small signal npn transistor preliminary data ordering code marking package / shipment 2n3904 2n3904 to-92 / bulk 2n3904-ap 2n3904 to-92 / ammopack silicon epitaxial planar npn transistor to-92 package suitable for through-hole pcb assembly the pnp complementary type is 2n3906 to-92 to-92 applications bulk ammopack well suitable for tv ...
