Here is an image showing the pin diagram of this transistor.The 2SD1250 transistor can have a current gain of 60 to 240. The gain of the 2SD1250-P will be in the range from 100 to 240, for the 2SD1250-Q it will be in the range from 60 to 140.Sometimes the "2S" prefix is not marked on the package - the 2SD1250 might only be marked "D1250".The complementary NPN transistor to the 2SD1250 is the 2SB928.You can replace the 2SD1250 with the 2SB928, 2SB928A or 2SD1250A.
