Here is an image showing the pin diagram of this transistor.The 2SD613-C transistor can have a current gain of 40 to 80. The gain of the 2SD613 will be in the range from 40 to 320, for the 2SD613-D it will be in the range from 60 to 120, for the 2SD613-E it will be in the range from 100 to 200, for the 2SD613-F it will be in the range from 160 to 320.Sometimes the "2S" prefix is not marked on the package - the 2SD613-C might only be marked "D613-C".The complementary PNP transistor to the 2SD613-C is the 2SB633-C.The BDP953 (SOT-223) is the SMD version of the 2SD613-C transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the 2SD613-C with the 2SC2334, 2SC2334M, 2SD363, 2SD363-R, 2SD823, BD243C, BD711, BD743C, BD801, BD911, BDT85, BDT85F, BDT87, BDT87F, BDT95, BDT95F, KSC2334, KSC2334R, KSD363, KSD363-R, MJE15028, MJE15028G, MJE15030, MJE15030G, MJE5180, MJE5181, MJE5182, MJF15030, MJF15030G, MJF3055, MJF3055G, TIP41D, TIP41E, TIP41F, TIP42D, TIP42E or TIP42F.
