Here is an image showing the pin diagram of this transistor.The 2SD2389 transistor can have a current gain of 5000 to 30000. The gain of the 2SD2389-O will be in the range from 5000 to 12000, for the 2SD2389-P it will be in the range from 6500 to 20000, for the 2SD2389-Y it will be in the range from 15000 to 30000.Sometimes the "2S" prefix is not marked on the package - the 2SD2389 might only be marked "D2389".The complementary PNP transistor to the 2SD2389 is the 2SB1559.You can replace the 2SD2389 with the 2SC2579, 2SD2390 or BDV67D.
