Here is an image showing the pin diagram of this transistor.The 2SD602A-Q transistor can have a current gain of 85 to 170. The gain of the 2SD602A will be in the range from 85 to 340, 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-Q might only be marked "D602A-Q".The complementary PNP transistor to the 2SD602A-Q is the 2SB710A-Q.You can replace the 2SD602A-Q with the 2SC3325, 2SC3912, 2SC3913, 2SC3914, 2SC3915, FMMTA05, FMMTA06, KST05 or KST06.
