Here is an image showing the pin diagram of this transistor.The 2SD1588-M transistor can have a current gain of 40 to 80. The gain of the 2SD1588 will be in the range from 40 to 200, for the 2SD1588-K it will be in the range from 100 to 200, for the 2SD1588-L it will be in the range from 80 to 120.Sometimes the "2S" prefix is not marked on the package - the 2SD1588-M might only be marked "D1588-M".The complementary PNP transistor to the 2SD1588-M is the 2SB1097-M.You can replace the 2SD1588-M with the 2N5496, 2N6098, 2N6099, 2N6100, 2N6101, 2N6130, 2N6131, 2N6292, 2N6292G, 2N6293, 2N6487, 2N6487G, 2N6488, 2N6488G, 2SC2334, 2SC2334M, 2SD568, 2SD568-M, 2SD569, 2SD569-M, BD203, BD303, BD535, BD535K, BD537, BD537K, BD707, BD709, BD711, BD743A, BD743B, BD743C, BD797, BD799, BD801, BD807, BD809, BD907, BD909, BD911, BDT81, BDT81F, BDT83, BDT83F, BDT85, BDT85F, BDT87, BDT87F, BDT91, BDT91F, BDT93, BDT93F, BDT95, BDT95F, BDX77, KSC2334, KSC2334R, KSD1588, KSD1588-R, KSD568, KSD568-R, KSD569, KSD569-R, MJE15028, MJE15028G, MJE2801T, MJE3055T, MJE3055TG, MJF3055, MJF3055G or NTE196.
