Here is an image showing the pin diagram of this transistor.The 2SC2785-EF transistor can have a current gain of 250 to 400. The gain of the 2SC2785 will be in the range from 110 to 600, for the 2SC2785-FF it will be in the range from 200 to 320, for the 2SC2785-HF it will be in the range from 170 to 270, for the 2SC2785-JF it will be in the range from 135 to 220, for the 2SC2785-KF it will be in the range from 300 to 600, for the 2SC2785-RF it will be in the range from 110 to 180.Sometimes the "2S" prefix is not marked on the package - the 2SC2785-EF might only be marked "C2785-EF".The complementary PNP transistor to the 2SC2785-EF is the 2SA1175-EF.The 2SC1623 (SOT-23), 2SC1623-L6 (SOT-23), 2SD601A (SOT-23), KSC1623 (SOT-23), KSC1623-G (SOT-23), KST2484 (SOT-23), MMBT2484 (SOT-23) and PMBT6428 (SOT-23) is the SMD version of the 2SC2785-EF transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the 2SC2785-EF with the 2N3417, 2SC1570, 2SC1815, 2SC1815GR, 2SC1843, 2SC1843P, 2SC1844, 2SC1844P, 2SC2002, 2SC2002-K, 2SC2003, 2SC2003-K, 2SC2396, 2SC2396-D, 2SC2458, 2SC2458-GR, 2SC2543, 2SC2543-D, 2SC2545, 2SC2545-D, 2SC2546, 2SC2546-D, 2SC2634, 2SC2960, 2SC3114, 2SC3114-T, 2SC3198, 2SC3198-GR, 2SC3199, 2SC3199-GR, 2SC3329, 2SC3329-GR, 2SC3330, 2SC3330-T, 2SC3331, 2SC3331-T, 2SC3382, 2SC3382-T, 2SC3383, 2SC3383-T, 2SC3708, 2SC3708-T, 2SC3916, 2SC3917, 2SC3918, 2SC3919, 2SC3920, 2SC3921, 2SC3922, 2SC3923, 2SC4408, 2SC4604, 2SC536N, 2SC6043, 2SC945, 2SC945P, 2SD1207, 2SD1207-T, 2SD1347, 2SD1347T, 2SD1616, 2SD1616-K, 2SD1616A, 2SD1616A-K, 2SD1835, 2SD1835-T, 2SD438, 2SD789, 2SD789-D, BC182L, BC182LB, C1815, C1815GR, C945, C945GR, H945, H945-P, KSC1008C, KSC1008CG, KSC1815, KSC1815GR, KSC945C, KSC945CG, KSD1616, KSD1616-G, KSD1616A, KSD1616A-G, KTC1006, KTC3198, KTC3198GR, KTC3199, KTC3199GR or NTE192A.
