Here is an image showing the pin diagram of this transistor.The 2SB940-Q transistor can have a current gain of 60 to 140. The gain of the 2SB940 will be in the range from 60 to 240, for the 2SB940-P it will be in the range from 100 to 240.Sometimes the "2S" prefix is not marked on the package - the 2SB940-Q might only be marked "B940-Q".The complementary NPN transistor to the 2SB940-Q is the 2SD1264-Q.You can replace the 2SB940-Q with the 2SA1667, 2SA1668, 2SA1859, 2SA1859A, 2SB546, 2SB546A, 2SB547, 2SB630, 2SB861, 2SB940A, 2SB940A-Q, FJP1943, FJPF1943, KSB546, MJE15031, MJE15031G, MJE15033, MJE15033G, MJE5850, MJE5850G, MJF15031 or MJF15031G.
