Here is an image showing the pin diagram of this transistor.The 2SD313E transistor can have a current gain of 100 to 200. The gain of the 2SD313 will be in the range from 40 to 320, for the 2SD313C it will be in the range from 40 to 80, for the 2SD313D it will be in the range from 60 to 120, for the 2SD313F it will be in the range from 160 to 320.Sometimes the "2S" prefix is not marked on the package - the 2SD313E might only be marked "D313E".The complementary PNP transistor to the 2SD313E is the 2SB507E.The BDP949 (SOT-223) is the SMD version of the 2SD313E transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the 2SD313E with the 2SC1826, 2SC1827, 2SC1985, 2SC1986, 2SC2075, 2SC2078, 2SC2078E, 2SC2334, 2SC2527, 2SC3179, 2SC3252, 2SC3252-R, 2SC3253, 2SC3253-R, 2SC3254, 2SC3254-R, 2SC3255, 2SC3255-R, 2SC3258, 2SC3308, 2SC3346, 2SC3540, 2SC3710, 2SC3710A, 2SC3746, 2SC3746-R, 2SC3747, 2SC3747-R, 2SC3748, 2SC3748-R, 2SC3834, 2SC3851, 2SC3851A, 2SC4007, 2SC4007-E, 2SC4008, 2SC4008-E, 2SC4153, 2SC4550, 2SC4550-M, 2SC4551, 2SC4551-M, 2SC4552, 2SC4552-M, 2SC789, 2SD1134, 2SD1134-C, 2SD1266, 2SD1266A, 2SD1267, 2SD1267A, 2SD1268, 2SD1269, 2SD1270, 2SD1271, 2SD1274, 2SD1274A, 2SD1274B, 2SD1354, 2SD1354-Y, 2SD1355, 2SD1356, 2SD1362, 2SD1406, 2SD1406-Y, 2SD1407, 2SD1407A, 2SD1408, 2SD1411, 2SD1411A, 2SD1568, 2SD1568-K, 2SD1588, 2SD1588-K, 2SD1666, 2SD1666-R, 2SD1761, 2SD1761-E, 2SD1913, 2SD1913R, 2SD2012, 2SD2058, 2SD2058-Y, 2SD2059, 2SD2060, 2SD2061, 2SD2374, 2SD2374A, 2SD2394, 2SD2394-E, 2SD363, 2SD476A, 2SD476A-C, 2SD525, 2SD526, 2SD568, 2SD568-K, 2SD569, 2SD569-K, 2SD613, 2SD613-E, 2SD743, 2SD743-Q, 2SD743A, 2SD743A-Q, 2SD812, 2SD812-P, 2SD823, 2SD856, 2SD856A, 2SD857, 2SD857A, 2SD866, 2SD866A, 2SD880, 2SD880Y, BD203, BD241A, BD241B, BD241C, BD243A, BD243B, BD243C, BD303, BD535, BD537, BD539A, BD539B, BD539C, BD539D, BD543A, BD543B, BD543C, BD545A, BD545B, BD545C, BD797, BD799, BD801, BD807, BD809, BD935, BD935F, BD937, BD937F, BD939, BD939F, BD941, BD941F, BD949, BD951, BD953, BD955, BDT81, BDT81F, BDT83, BDT83F, BDT85, BDT85F, BDT87, BDT87F, BDT91, BDT91F, BDT93, BDT93F, BDT95, BDT95F, BDX77, D44H11, D44H11FP, D44H8, KSC2334, KSD1406, KSD1406-Y, KSD1408, KSD1588, KSD1588-Y, KSD2012, KSD2012-Y, KSD2058, KSD2058-Y, KSD363, KSD526, KSD568, KSD568-Y, KSD569, KSD569-Y, KSD880, KSD880-Y, KTC2016, KTC2016-Y, KTC2018, KTC2026, KTC2026-Y, KTC2026Y, KTC2027, KTC2028, KTD1351, KTD1351Y, KTD2058, KTD2058Y, KTD2059, KTD2060, MJE15028, MJE15028G, NTE152, TIP41D or TIP42D.
