Here is an image showing the pin diagram of this transistor.The 2SC3502-E transistor can have a current gain of 100 to 200. The gain of the 2SC3502 will be in the range from 40 to 320, for the 2SC3502-C it will be in the range from 40 to 80, for the 2SC3502-D it will be in the range from 60 to 120, for the 2SC3502-F it will be in the range from 160 to 320.Sometimes the "2S" prefix is not marked on the package - the 2SC3502-E might only be marked "C3502-E".The complementary PNP transistor to the 2SC3502-E is the 2SA1380-E.The BF622 (SOT-89) and BF822 (SOT-23) is the SMD version of the 2SC3502-E transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the 2SC3502-E with the 2N5655, 2N5655G, 2N5656, 2N5656G, 2N5657, 2N5657G, 2SC2258, 2SC2688, 2SC2688-L, 2SC2899, 2SC2912, 2SC2912-R, 2SC3416, 2SC3416-E, 2SC3417, 2SC3417-E, 2SC3503, 2SC3503-E, 2SC3600, 2SC3600-E, 2SC3601, 2SC3601-E, 2SC3788, 2SC3788-E, 2SC3789, 2SC3789-E, 2SC3790, 2SC3790-E, 2SC3955, 2SC3955-E, 2SC3956, 2SC3956-E, 2SC4212, 2SD1610, 2SD1610-C, BD127, BD128, BD129, BD157, BD158, BD159, BD410, BUX86, KSC2258, KSC2258A, KSC2688, KSC2688-Y, KSC3502, KSC3502-E, KSC3503, KSC3503-E, KSE340, MJE340, MJE340G, MJE3439, MJE3439G, MJE344, MJE3440 or MJE344G.
