Here is an image showing the pin diagram of this transistor.The 2SB947A-R transistor can have a current gain of 60 to 120. The gain of the 2SB947A will be in the range from 60 to 260, for the 2SB947A-P it will be in the range from 130 to 260, for the 2SB947A-Q it will be in the range from 90 to 180.Sometimes the "2S" prefix is not marked on the package - the 2SB947A-R might only be marked "B947A-R".You can replace the 2SB947A-R with the 2N6489, 2N6489G, 2N6490, 2N6490G, 2N6491, 2N6491G, 2SB948A, 2SB948A-R, BD546, BD546A, BD546B, BD706, BD708, BD710, BD744, BD744A, BD744B, BD808, BD810, BD906, BD908, BD910, BDT82, BDT82F, BDT84, BDT84F, BDT92, BDT92F, BDT94, BDT94F, D45H11, D45H11FP or D45H8.
