Here is an image showing the pin diagram of this transistor.The 2SC3790-F transistor can have a current gain of 160 to 320. The gain of the 2SC3790 will be in the range from 40 to 320, for the 2SC3790-C it will be in the range from 40 to 80, for the 2SC3790-D it will be in the range from 60 to 120, for the 2SC3790-E it will be in the range from 100 to 200.Sometimes the "2S" prefix is not marked on the package - the 2SC3790-F might only be marked "C3790-F".The complementary PNP transistor to the 2SC3790-F is the 2SA1480-F.The BF620 (SOT-89), BF820 (SOT-23) and PMBTA42 (SOT-23) is the SMD version of the 2SC3790-F transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the 2SC3790-F with the 2SC2899, 2SC3417, 2SC3417-F, 2SC3503, 2SC3503-F, 2SC3789, 2SC3789-F, BD128, BD129, BUX86, BUX87, KSC2258A, KSC3503 or KSC3503-F.
