Here is an image showing the pin diagram of this transistor.The 2SD1761-D transistor can have a current gain of 60 to 120. The gain of the 2SD1761 will be in the range from 60 to 320, for the 2SD1761-E it will be in the range from 100 to 200, for the 2SD1761-F it will be in the range from 160 to 320.Sometimes the "2S" prefix is not marked on the package - the 2SD1761-D might only be marked "D1761-D".The complementary PNP transistor to the 2SD1761-D is the 2SB1187-D.You can replace the 2SD1761-D with the 2N5293, 2N5294, 2N6292, 2N6292G, 2N6293, 2N6473, 2N6474, 2N6487, 2N6487G, 2N6488, 2N6488G, 2SC1826, 2SC1827, 2SC1985, 2SC1986, 2SC2075, 2SC2078, 2SC2078D, 2SC2233, 2SC2334, 2SC2527, 2SC3179, 2SC3851, 2SC3851A, 2SC4511, 2SC4512, 2SC789, 2SD1134, 2SD1134-B, 2SD1265, 2SD1265A, 2SD1267, 2SD1267A, 2SD1268, 2SD1268-R, 2SD1269, 2SD1269-R, 2SD1270, 2SD1270-R, 2SD1271, 2SD1271-R, 2SD1274, 2SD1274A, 2SD1274B, 2SD1354, 2SD1354-O, 2SD1355, 2SD1356, 2SD1406, 2SD1406-O, 2SD1407, 2SD1407A, 2SD1408, 2SD1568, 2SD1588, 2SD2058, 2SD2058-O, 2SD2059, 2SD2060, 2SD313, 2SD313D, 2SD362, 2SD363, 2SD389, 2SD389A, 2SD476A, 2SD476A-B, 2SD525, 2SD526, 2SD568, 2SD568-L, 2SD569, 2SD569-L, 2SD613, 2SD613-D, 2SD743, 2SD743-R, 2SD743A, 2SD743A-R, 2SD812, 2SD812-Q, 2SD823, 2SD856, 2SD856A, 2SD857, 2SD857A, 2SD866, 2SD866-R, 2SD866A, 2SD866A-R, 2SD880, 2SD880O, BD203, BD241A, BD241B, BD241C, BD243A, BD243B, BD243C, BD303, BD535, BD537, BD539A, BD539B, BD539C, BD539D, BD543A, BD543B, BD543C, BD545A, BD545B, BD545C, BD707, BD709, BD711, BD743A, BD743B, BD743C, BD797, BD799, BD801, BD807, BD809, BD907, BD909, BD911, 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-O, KSD1408, KSD1588, KSD2058, KSD2058-O, KSD362, KSD363, KSD526, KSD568, KSD568-O, KSD569, KSD569-O, KSD880, KSD880-O, KTC1003, KTD1351, KTD1351O, KTD2058, KTD2058O, KTD2059, KTD2060, MJE15028, MJE15028G, NTE152, NTE196, TIP41D or TIP42D.
