Covering the 2SC5472, this 38.0 KB PDF carries an _E suffix that probably means an English edition. Under Japanese JIS numbering the 2SC prefix denotes an NPN bipolar transistor, so the content is likely a datasheet despite the schematic category. It lists the ratings, characteristics and package details needed when replacing a damaged transistor. Check the device marking, compare collector-emitter voltage and current with any candidate equivalent, and verify the pinout, since pin order can vary between manufacturers.
