Here is an image showing the pin diagram of this transistor.The 2SC2784-U transistor can have a current gain of 600 to 1200. The gain of the 2SC2784 will be in the range from 200 to 1200, for the 2SC2784-E it will be in the range from 400 to 800, for the 2SC2784-F it will be in the range from 300 to 600, for the 2SC2784-P it will be in the range from 200 to 400.Sometimes the "2S" prefix is not marked on the package - the 2SC2784-U might only be marked "C2784-U".The FJV1845 (SOT-23) and FJV1845-U (SOT-23) is the SMD version of the 2SC2784-U transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the 2SC2784-U with the 2SC1775A, 2SC1775A-F, 2SC1841, 2SC1841U, 2SC1845, 2SC1845U, 2SC1890A, 2SC1890A-F, 2SC2544, KSC1845 or KSC1845U.
