Here is an image showing the pin diagram of this transistor.
Classification of hFE
The 2SB1158 transistor can have a current gain of 60 to 200. The gain of the 2SB1158-P will be in the range from 100 to 200, for the 2SB1158-Q it will be in the range from 60 to 120, for the 2SB1158-S it will be in the range from 80 to 160.
Marking
Sometimes the "2S" prefix is not marked on the package - the 2SB1158 might only be marked "B1158".
Complementary NPN transistor
The complementary NPN transistor to the 2SB1158 is the 2SD1713.
SMD Version of 2SB1158 transistor
The BDP956 (SOT-223) is the SMD version of the 2SB1158 transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.
