Here is an image showing the pin diagram of this transistor.The 2SD1264A transistor can have a current gain of 60 to 240. The gain of the 2SD1264A-P will be in the range from 100 to 240, for the 2SD1264A-Q it will be in the range from 60 to 140.Sometimes the "2S" prefix is not marked on the package - the 2SD1264A might only be marked "D1264A".The complementary PNP transistor to the 2SD1264A is the 2SB940A.You can replace the 2SD1264A with the 2SC4382, 2SC4883A, 2SD772A, 2SD772B, 2SD792A, 2SD792B, MJE15032 or MJE15032G.
