Here is an image showing the pin diagram of this transistor.The 2SB647D transistor can have a current gain of 160 to 320. The gain of the 2SB647 will be in the range from 60 to 320, for the 2SB647B it will be in the range from 60 to 120, for the 2SB647C it will be in the range from 100 to 200.Sometimes the "2S" prefix is not marked on the package - the 2SB647D might only be marked "B647D".The complementary NPN transistor to the 2SB647D is the 2SD667D.You can replace the 2SB647D with the 2SA1275, 2SA1275-Y, KSA1013, KSA1013Y, KTA1275, KTA1275Y or NTE383.
