Here is an image showing the pin diagram of this transistor.The 2SB940A transistor can have a current gain of 60 to 240. The gain of the 2SB940A-P will be in the range from 100 to 240, for the 2SB940A-Q it will be in the range from 60 to 140.Sometimes the "2S" prefix is not marked on the package - the 2SB940A might only be marked "B940A".The complementary NPN transistor to the 2SB940A is the 2SD1264A.You can replace the 2SB940A with the 2SA1668, 2SA1859A, MJE15033, MJE15033G, MJE5850, MJE5850G, MJE5851 or MJE5851G.
