Here is an image showing the pin diagram of this transistor.The 2SD2061E transistor can have a current gain of 100 to 200. The gain of the 2SD2061 will be in the range from 100 to 320, for the 2SD2061F it will be in the range from 160 to 320.Sometimes the "2S" prefix is not marked on the package - the 2SD2061E might only be marked "D2061E".The 2SD1623 (SOT-89), 2SD1623-R (SOT-89), 2SD1624 (SOT-89), 2SD1624-R (SOT-89) and BDP949 (SOT-223) is the SMD version of the 2SD2061E transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the 2SD2061E with the 2SC1061, 2SC1061-C, 2SC1826, 2SC1827, 2SC1985, 2SC1986, 2SC2075, 2SC2078, 2SC2078E, 2SC2334, 2SC2562, 2SC3179, 2SC3239, 2SC3252, 2SC3252-R, 2SC3253, 2SC3253-R, 2SC3254, 2SC3254-R, 2SC3255, 2SC3255-R, 2SC3258, 2SC3299, 2SC3308, 2SC3345, 2SC3346, 2SC3540, 2SC3709, 2SC3709A, 2SC3710, 2SC3710A, 2SC3746, 2SC3746-R, 2SC3747, 2SC3747-R, 2SC3748, 2SC3748-R, 2SC3851, 2SC3851A, 2SC4007, 2SC4007-E, 2SC4008, 2SC4008-E, 2SC4550, 2SC4550-M, 2SC4551, 2SC4551-M, 2SC4552, 2SC4552-M, 2SC4881, 2SC4935, 2SC789, 2SD1060, 2SD1060-R, 2SD1061, 2SD1061-R, 2SD1062, 2SD1062-R, 2SD1133, 2SD1133-C, 2SD1134, 2SD1134-C, 2SD1266, 2SD1266A, 2SD1267, 2SD1267A, 2SD1268, 2SD1269, 2SD1270, 2SD1271, 2SD1274, 2SD1274A, 2SD1274B, 2SD1354, 2SD1354-Y, 2SD1355, 2SD1356, 2SD1362, 2SD1363, 2SD1406, 2SD1406-Y, 2SD1407, 2SD1407A, 2SD1408, 2SD1411, 2SD1411A, 2SD1412, 2SD1568, 2SD1568-K, 2SD1588, 2SD1588-K, 2SD1666, 2SD1666-R, 2SD1667, 2SD1667-R, 2SD1668, 2SD1668-R, 2SD1669, 2SD1669-R, 2SD1761, 2SD1761-E, 2SD1762, 2SD1762E, 2SD1913, 2SD1913R, 2SD2012, 2SD2058, 2SD2058-Y, 2SD2059, 2SD2060, 2SD234, 2SD2374, 2SD2374A, 2SD2394, 2SD2394-E, 2SD2395, 2SD2395-E, 2SD288, 2SD313, 2SD313E, 2SD476, 2SD476-C, 2SD476A, 2SD476A-C, 2SD525, 2SD526, 2SD553, 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, BD543A, BD543B, BD543C, BD545A, BD545B, BD545C, BD797, BD799, BD801, BD807, BD809, BD935, BD935F, BD937, BD937F, BD939, BD939F, BD949, BD951, BD953, BDT81, BDT81F, BDT83, BDT83F, BDT85, BDT85F, BDT91, BDT91F, BDT93, BDT93F, BDT95, BDT95F, BDX77, D44H11, D44H11FP, D44H8, KSC2334, KSD1406, KSD1406-Y, KSD1408, KSD1588, KSD1588-Y, KSD2012, KSD2012-Y, KSD2058, KSD2058-Y, KSD288, 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 or NTE152.
