Here is an image showing the pin diagram of this transistor.The 2SD389 transistor can have a current gain of 30 to 160. The gain of the 2SD389-O will be in the range from 80 to 160, for the 2SD389-P it will be in the range from 50 to 100, for the 2SD389-Q it will be in the range from 30 to 60.Sometimes the "2S" prefix is not marked on the package - the 2SD389 might only be marked "D389".You can replace the 2SD389 with the 2SC2075, 2SD1265, 2SD1265A, 2SD1274, 2SD1274A, 2SD1274B, 2SD389A, 2SD823, BD203, BD243A, BD243B, BD243C, BD303, BD797, BD799, BD801, BD807, BD809, BDT91, BDT91F, BDT93, BDT93F, BDT95, BDT95F, BDX77, TIP41D or TIP42D.
