A 126 KB PDF for the 2SC5096FT, which adds an FT suffix to the base type 2SC5096. Under JEITA naming the 2SC prefix denotes an NPN bipolar transistor, and suffixes like this usually point to a package or version variant, though the name does not explain it. Expect a datasheet with ratings, pinout and outline dimensions. Compare it with the plain 2SC5096 sheet and check the footprint and marking on the board, because suffix variants can differ in package and lead order.
