Here is an image showing the pin diagram of this transistor.The 2SB647AB transistor can have a current gain of 60 to 120. The gain of the 2SB647A will be in the range from 60 to 200, for the 2SB647AC it will be in the range from 100 to 200.Sometimes the "2S" prefix is not marked on the package - the 2SB647AB might only be marked "B647AB".The complementary NPN transistor to the 2SB647AB is the 2SD667AB.You can replace the 2SB647AB with the 2SA1013, 2SA1013R, 2SA1275, 2SA1275-R, KSA1013, KSA1013R, KTA1275 or KTA1275R.
