Device datasheet in PDF form, 297 KB, for the 2SC5096, though the catalogue lists it as a schematic. The 2SC prefix is the JEITA code for an NPN bipolar transistor, and the name provides no further detail such as maker or package. Look here for absolute maximum ratings, hFE, characteristic graphs and dimensions. A separate FT-suffixed variant of this type also exists, so check the exact marking and package on the PCB before relying on pinout or footprint information from this sheet.
