Here is an image showing the pin diagram of this transistor.The 2SC2784-F transistor can have a current gain of 300 to 600. 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-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-F might only be marked "C2784-F".The complementary PNP transistor to the 2SC2784-F is the 2SA1174-F.The 2SC1622A (SOT-23), 2SC1622A-D17 (SOT-23), FJV1845 (SOT-23) and FJV1845-F (SOT-23) is the SMD version of the 2SC2784-F transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the 2SC2784-F with the 2SC1841, 2SC1841F, 2SC1845, 2SC1845F, 2SC1890A, 2SC2240, 2SC2326K, 2SC2459, 2SC2544, 2SC2547, 2SC3200, 2SC3201, 2SC3245, 2SC3245A, 2SC3478, 2SC3478-U, 2SD756, KSC1845, KSC1845F or KTC3200.
