PDF file of 129 KB titled with the part number 2SC5228, catalogued as a schematic but best treated as a transistor datasheet. Within JIS naming, the 2SC series covers NPN bipolar transistors. Nothing else is encoded in the name. Consult it for the case outline, pin order, voltage and current maxima and gain classes. Then compare the code stamped on the faulty part with this number before ordering, since adjacent numbers in the range are unrelated devices.
