Here is an image showing the pin diagram of this transistor.The 2SD602A transistor can have a current gain of 85 to 340. The gain of the 2SD602A-Q will be in the range from 85 to 170, for the 2SD602A-R it will be in the range from 120 to 240, for the 2SD602A-S it will be in the range from 170 to 340.Sometimes the "2S" prefix is not marked on the package - the 2SD602A might only be marked "D602A".The complementary PNP transistor to the 2SD602A is the 2SB710A.You can replace the 2SD602A with the 2SC3912, 2SC3913, 2SC3914, 2SC3915, FMMTA05, FMMTA06, KST05 or KST06.
