Here is an image showing the pin diagram of this transistor.The 2SD753-A transistor can have a current gain of 35 to 70. The gain of the 2SD753 will be in the range from 35 to 200, for the 2SD753-B it will be in the range from 60 to 120, for the 2SD753-C it will be in the range from 100 to 200.Sometimes the "2S" prefix is not marked on the package - the 2SD753-A might only be marked "D753-A".The complementary PNP transistor to the 2SD753-A is the 2SB723-A.You can replace the 2SD753-A with the 2N6676, 2N6677, 2N6678, BUX48, MJ21194, MJ21194G, MJ21196 or MJ21196G.
