Here is an image showing the pin diagram of this transistor.The 2SD753 transistor can have a current gain of 35 to 200. The gain of the 2SD753-A will be in the range from 35 to 70, 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 might only be marked "D753".The complementary PNP transistor to the 2SD753 is the 2SB723.You can replace the 2SD753 with the 2N6676, 2N6677, 2N6678 or BUX48.
