Here is an image showing the pin diagram of this transistor.The 2SD1588 transistor can have a current gain of 40 to 200. The gain of the 2SD1588-K will be in the range from 100 to 200, for the 2SD1588-L it will be in the range from 80 to 120, for the 2SD1588-M it will be in the range from 40 to 80.Sometimes the "2S" prefix is not marked on the package - the 2SD1588 might only be marked "D1588".The complementary PNP transistor to the 2SD1588 is the 2SB1097.You can replace the 2SD1588 with the 2SC2334, 2SD568, 2SD569, BD203, BD303, BD535, BD537, BD797, BD799, BD801, BD807, BD809, BDT81, BDT81F, BDT83, BDT83F, BDT85, BDT85F, BDT87, BDT87F, BDT91, BDT91F, BDT93, BDT93F, BDT95, BDT95F, BDX77, KSC2334, KSD1588, KSD568, KSD569, MJE15028 or MJE15028G.
