Here is an image showing the pin diagram of this transistor.The 2SC2784 transistor can have a current gain of 200 to 1200. The gain of the 2SC2784-E 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, for the 2SC2784-U it will be in the range from 600 to 1200.Sometimes the "2S" prefix is not marked on the package - the 2SC2784 might only be marked "C2784".The complementary PNP transistor to the 2SC2784 is the 2SA1174.The FJV1845 (SOT-23) is the SMD version of the 2SC2784 transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the 2SC2784 with the 2SC1841, 2SC1845 or KSC1845.
