Here is an image showing the pin diagram of this transistor.The 2SC2785-KF transistor can have a current gain of 300 to 600. The gain of the 2SC2785 will be in the range from 110 to 600, for the 2SC2785-EF it will be in the range from 250 to 400, 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-RF it will be in the range from 110 to 180.Sometimes the "2S" prefix is not marked on the package - the 2SC2785-KF might only be marked "C2785-KF".The complementary PNP transistor to the 2SC2785-KF is the 2SA1175-KF.The 2SC1623 (SOT-23), 2SC1623-L7 (SOT-23), KSC1623 (SOT-23), KSC1623-L (SOT-23), KST2484 (SOT-23) and PMBT6428 (SOT-23) is the SMD version of the 2SC2785-KF transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the 2SC2785-KF with the 2SC1570, 2SC1815, 2SC1843, 2SC1843F, 2SC1844, 2SC1844F, 2SC2396, 2SC2458, 2SC2458-BL, 2SC2543, 2SC2545, 2SC2546, 2SC2634, 2SC3198, 2SC3198-BL, 2SC3199, 2SC3199-BL, 2SC3329, 2SC3330, 2SC3331, 2SC3916, 2SC3917, 2SC3918, 2SC3919, 2SC3920, 2SC3921, 2SC3922, 2SC3923, 2SC945, 2SC945K, 2SD1616, 2SD1616-U, 2SD1616A-U, 2SD789, BC182LB, C1815, C945, H945, H945-K, KSC1815, KSC945C, KSD1616, KSD1616-L, KTC1006, KTC3198, KTC3198BL, KTC3199 or KTC3199BL.
