Here is an image showing the pin diagram of this transistor.The 2SD1895 transistor can have a current gain of 5000 to 30000. The gain of the 2SD1895-P will be in the range from 5000 to 15000, for the 2SD1895-Q it will be in the range from 8000 to 30000.Sometimes the "2S" prefix is not marked on the package - the 2SD1895 might only be marked "D1895".The complementary PNP transistor to the 2SD1895 is the 2SB1255.
