Here is an image showing the pin diagram of this transistor.The 2SD1264 transistor can have a current gain of 60 to 240. The gain of the 2SD1264-P will be in the range from 100 to 240, for the 2SD1264-Q it will be in the range from 60 to 140.Sometimes the "2S" prefix is not marked on the package - the 2SD1264 might only be marked "D1264".The complementary PNP transistor to the 2SD1264 is the 2SB940.You can replace the 2SD1264 with the 2SC4381, 2SC4382, 2SC4883, 2SC4883A, 2SD1138, 2SD1264A, 2SD401, 2SD402, 2SD772, 2SD772A, 2SD772B, 2SD792, 2SD792A, 2SD792B, MJE15030, MJE15030G, MJE15032, MJE15032G, MJF15030, MJF15030G, TIP41F or TIP42F.
