Here is an image showing the pin diagram of this transistor.
Classification of hFE
The 2SB941 transistor can have a current gain of 70 to 250. The gain of the 2SB941-P will be in the range from 120 to 250, for the 2SB941-Q it will be in the range from 70 to 150.
Marking
Sometimes the "2S" prefix is not marked on the package - the 2SB941 might only be marked "B941".
Complementary NPN transistor
The complementary NPN transistor to the 2SB941 is the 2SD1266.
