Here is an image showing the pin diagram of this transistor.The 2SD1355-R transistor can have a current gain of 40 to 80. The gain of the 2SD1355 will be in the range from 40 to 240, for the 2SD1355-O it will be in the range from 70 to 140, for the 2SD1355-Y it will be in the range from 120 to 240.Sometimes the "2S" prefix is not marked on the package - the 2SD1355-R might only be marked "D1355-R".The complementary PNP transistor to the 2SD1355-R is the 2SB995-R.The BDP953 (SOT-223) is the SMD version of the 2SD1355-R transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the 2SD1355-R with the 2SC2334, 2SC2334M, 2SD1407, 2SD1407-R, 2SD1407A, 2SD1407A-R, 2SD2059, 2SD2059-R, 2SD363, 2SD363-R, 2SD525, 2SD525-R, 2SD772, 2SD772A, 2SD792, 2SD792A, BD243C, BD539C, BD539D, BD711, BD743C, BD801, BD911, BD953, BD955, BDT85, BDT85F, BDT87, BDT87F, BDT95, BDT95F, KSC2334, KSC2334R, KSD363, KSD363-R, KTD2059, KTD2059R, MJE15028, MJE15028G, MJE15030, MJE15030G, MJE5180, MJE5181, MJE5182, MJF15030, MJF15030G, TIP41D, TIP41E, TIP41F, TIP42D, TIP42E or TIP42F.
