Here is an image showing the pin diagram of this transistor.The 2SD746A-R transistor can have a current gain of 60 to 120. 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-S it will be in the range from 40 to 80.Sometimes the "2S" prefix is not marked on the package - the 2SD746A-R might only be marked "D746A-R".The complementary PNP transistor to the 2SD746A-R is the 2SB706A-R.You can replace the 2SD746A-R with the 2N6676, 2N6677, 2N6678, BUX48, BUX80, BUY69A, BUY69B, BUY70A, BUY70B, MJ10000, MJ10001, MJ15011 or MJ15011G.
