Here is an image showing the pin diagram of this transistor.The 2SD746A-S transistor can have a current gain of 40 to 80. The gain of the 2SD746A will be in the range from 40 to 200, for the 2SD746A-Q it will be in the range from 100 to 200, for the 2SD746A-R it will be in the range from 60 to 120.Sometimes the "2S" prefix is not marked on the package - the 2SD746A-S might only be marked "D746A-S".The complementary PNP transistor to the 2SD746A-S is the 2SB706A-S.You can replace the 2SD746A-S with the 2N6676, 2N6677, 2N6678, BUX48, BUX80, BUY69A, BUY69B, BUY70A, BUY70B, MJ15011, MJ15011G, MJ413 or MJ423.
