Here is an image showing the pin diagram of this transistor.The 2SC2784-E transistor can have a current gain of 400 to 800. The gain of the 2SC2784 will be in the range from 200 to 1200, 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-E might only be marked "C2784-E".The complementary PNP transistor to the 2SC2784-E is the 2SA1174-E.The 2SC1622A (SOT-23), FJV1845 (SOT-23) and FJV1845-E (SOT-23) is the SMD version of the 2SC2784-E transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the 2SC2784-E with the 2SC1775A, 2SC1775A-E, 2SC1841, 2SC1841E, 2SC1845, 2SC1845E, 2SC1890A, 2SC1890A-E, 2SC2326K, 2SC2544, 2SC2544-E, 2SC2547, 2SC2547-E, 2SC3245, 2SC3245-G, 2SC3245A, 2SD756, 2SD756-E, KSC1845 or KSC1845E.
