Here is an image showing the pin diagram of this transistor.The 2SD613-E transistor can have a current gain of 100 to 200. The gain of the 2SD613 will be in the range from 40 to 320, for the 2SD613-C it will be in the range from 40 to 80, for the 2SD613-D it will be in the range from 60 to 120, 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-E might only be marked "D613-E".The complementary PNP transistor to the 2SD613-E is the 2SB633-E.The BDP953 (SOT-223) is the SMD version of the 2SD613-E transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the 2SD613-E with the 2SC2334, 2SC2527, 2SC3834, 2SC4153, 2SD363, 2SD823, 2SD866A, BD243C, BD543C, BD545C, BD801, BDT85, BDT85F, BDT87, BDT87F, BDT95, BDT95F, KSC2334, KSD363, MJE15028, MJE15028G, MJE15030, MJE15030G, MJF15030, MJF15030G, TIP41D, TIP41E, TIP41F, TIP42D, TIP42E or TIP42F.
