Here is an image showing the pin diagram of this transistor.The 2SB1168-R transistor can have a current gain of 100 to 200. The gain of the 2SB1168 will be in the range from 70 to 400, for the 2SB1168-Q it will be in the range from 70 to 140, for the 2SB1168-S it will be in the range from 140 to 280, for the 2SB1168-T it will be in the range from 200 to 400.Sometimes the "2S" prefix is not marked on the package - the 2SB1168-R might only be marked "B1168-R".The complementary NPN transistor to the 2SB1168-R is the 2SD1725-R.The BDP954 (SOT-223) and BDP956 (SOT-223) is the SMD version of the 2SB1168-R transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the 2SB1168-R with the BD792 or MJE254.
