Here is an image showing the pin diagram of this transistor.The 2SC3709A-Y transistor can have a current gain of 120 to 240. The gain of the 2SC3709A will be in the range from 70 to 240, for the 2SC3709A-O it will be in the range from 70 to 140.Sometimes the "2S" prefix is not marked on the package - the 2SC3709A-Y might only be marked "C3709A-Y".The complementary PNP transistor to the 2SC3709A-Y is the 2SA1451A-Y.You can replace the 2SC3709A-Y with the 2SC3345, 2SC3345-Y, 2SC3346, 2SC3346-Y, 2SC3709, 2SC3709-Y, 2SC3710, 2SC3710-Y, 2SC3710A, 2SC3710A-Y, 2SC4552, 2SD1062, 2SD1669, BD545A, BD545B, BD545C, BDT81, BDT81F, BDT83, BDT83F, BDT85, BDT85F or TTC3710B.
