Here is an image showing the pin diagram of this transistor.The 2SC3858 transistor can have a current gain of 50 to 180. The gain of the 2SC3858-O will be in the range from 50 to 100, for the 2SC3858-P it will be in the range from 70 to 140, for the 2SC3858-Y it will be in the range from 90 to 180.Sometimes the "2S" prefix is not marked on the package - the 2SC3858 might only be marked "C3858".The complementary PNP transistor to the 2SC3858 is the 2SA1494.
