Here is an image showing the pin diagram of this transistor.The 2SB647AC transistor can have a current gain of 100 to 200. The gain of the 2SB647A will be in the range from 60 to 200, for the 2SB647AB it will be in the range from 60 to 120.Sometimes the "2S" prefix is not marked on the package - the 2SB647AC might only be marked "B647AC".The complementary NPN transistor to the 2SB647AC is the 2SD667AC.The 2SA1201 (SOT-89), 2SB806 (SOT-89), 2SB806-KR (SOT-89), 2SD1007 (SOT-89), 2SD1007-HR (SOT-89) and KTA1661 (SOT-89) is the SMD version of the 2SB647AC transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the 2SB647AC with the 2SA1013, 2SA1013O, 2SA1275, 2SA1275-O, 2SA965, KSA1013, KSA1013O, KTA1275 or KTA1275O.
