Here is an image showing the pin diagram of this transistor.The 2SC2859 transistor can have a current gain of 70 to 400. The gain of the 2SC2859-GR will be in the range from 200 to 400, for the 2SC2859-O it will be in the range from 70 to 140, for the 2SC2859-Y it will be in the range from 120 to 240.Sometimes the "2S" prefix is not marked on the package - the 2SC2859 might only be marked "C2859".The complementary PNP transistor to the 2SC2859 is the 2SA1182.You can replace the 2SC2859 with the 2SC3912, 2SC3913, 2SC3914, 2SC3915, FMMTA05, KST05, KTC3876 or KTC3876S.
