Here is an image showing the pin diagram of this transistor.The 2SD1615A transistor can have a current gain of 135 to 400. The gain of the 2SD1615A-GP will be in the range from 200 to 400, for the 2SD1615A-GQ it will be in the range from 135 to 270.Sometimes the "2S" prefix is not marked on the package - the 2SD1615A might only be marked "D1615A".The complementary PNP transistor to the 2SD1615A is the 2SB1115A.
