Here is an image showing the pin diagram of this transistor.The 2SA1156 transistor can have a current gain of 30 to 200. The gain of the 2SA1156K will be in the range from 100 to 200, for the 2SA1156L it will be in the range from 60 to 120, for the 2SA1156M it will be in the range from 40 to 80, for the 2SA1156N it will be in the range from 30 to 60.Sometimes the "2S" prefix is not marked on the package - the 2SA1156 might only be marked "A1156".The complementary NPN transistor to the 2SA1156 is the 2SC2752.You can replace the 2SA1156 with the KSA1156.
