Here is an image showing the pin diagram of this transistor.The 2SB906-Y transistor can have a current gain of 100 to 200. The gain of the 2SB906 will be in the range from 60 to 200, for the 2SB906-O it will be in the range from 60 to 120.Sometimes the "2S" prefix is not marked on the package - the 2SB906-Y might only be marked "B906-Y".The complementary NPN transistor to the 2SB906-Y is the 2SD1221-Y.The BDP950 (SOT-223) is the SMD version of the 2SB906-Y transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the 2SB906-Y with the 2SB929, 2SB929A, 2SB930, 2SB930A, 2SB931, 2SB932, 2SB933, 2SB934, KTA1040D, KTA1040D-Y, KTA1042D, KTA1046 or KTA1046-Y.
