Here is an image showing the pin diagram of this transistor.The 2SB906 transistor can have a current gain of 60 to 200. The gain of the 2SB906-O will be in the range from 60 to 120, for the 2SB906-Y it will be in the range from 100 to 200.Sometimes the "2S" prefix is not marked on the package - the 2SB906 might only be marked "B906".The complementary NPN transistor to the 2SB906 is the 2SD1221.
