Here is an image showing the pin diagram of this transistor.The 2SD2061F transistor can have a current gain of 160 to 320. The gain of the 2SD2061 will be in the range from 100 to 320, for the 2SD2061E it will be in the range from 100 to 200.Sometimes the "2S" prefix is not marked on the package - the 2SD2061F might only be marked "D2061F".The 2SD1623 (SOT-89), 2SD1624 (SOT-89) and BDP949 (SOT-223) is the SMD version of the 2SD2061F transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the 2SD2061F with the 2SC1061, 2SC1061-D, 2SC1826, 2SC1985, 2SC1986, 2SC2075, 2SC3179, 2SC3851, 2SC3851A, 2SC4007, 2SC4007-F, 2SC4008, 2SC4008-F, 2SC4550, 2SC4551, 2SC4552, 2SD1133, 2SD1133-D, 2SD1134, 2SD1134-D, 2SD1266, 2SD1266-O, 2SD1266A, 2SD1266A-O, 2SD1274, 2SD1274A, 2SD1274B, 2SD1761, 2SD1761-F, 2SD1762, 2SD1762F, 2SD2012, 2SD2394, 2SD2394-F, 2SD2395, 2SD2395-F, 2SD313, 2SD313F, 2SD613, 2SD613-F, 2SD823, BD203, BD241A, BD241B, BD241C, BD243A, BD243B, BD243C, BD303, BD535, BD537, BD539A, BD539B, BD539C, BD543A, BD543B, BD543C, BD545A, BD545B, BD545C, BD797, BD799, BD801, BD807, BD809, BD949, BD951, BD953, BDT81, BDT81F, BDT83, BDT83F, BDT85, BDT85F, BDX77, D44H11, D44H11FP, D44H8, KSD2012 or KSD2012-G.
