Here is an image showing the pin diagram of this transistor.The 2SB948A transistor can have a current gain of 60 to 260. The gain of the 2SB948A-P will be in the range from 130 to 260, for the 2SB948A-Q it will be in the range from 90 to 180, for the 2SB948A-R it will be in the range from 60 to 120.Sometimes the "2S" prefix is not marked on the package - the 2SB948A might only be marked "B948A".The complementary NPN transistor to the 2SB948A is the 2SD1445A.You can replace the 2SB948A with the 2SB947A, BD546, BD546A, BD546B, BD808, BD810, BDT82, BDT82F, BDT84, BDT84F, D45H11, D45H11FP or D45H8.
