Here is an image showing the pin diagram of this transistor.The 2SC2785 transistor can have a current gain of 110 to 600. The gain of the 2SC2785-EF 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-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 might only be marked "C2785".The complementary PNP transistor to the 2SC2785 is the 2SA1175.The 2SC1623 (SOT-23) and KSC1623 (SOT-23) is the SMD version of the 2SC2785 transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the 2SC2785 with the 2SC1815, 2SC2458, 2SC3198, 2SC3199, 2SC3330, 2SC3331, 2SC3916, 2SC3917, 2SC3918, 2SC3919, 2SC3920, 2SC3921, 2SC3922, 2SC3923, 2SC945, 2SD789, BC182LB, C1815, C945, H945, KSC1815, KSC945C, KTC1006, KTC3198 or KTC3199.
