Small 41 KB PDF for the 2SC5190, with an _E suffix that may denote an English-language edition, though the name does not state this. The 2SC prefix is the JIS designation for NPN high-frequency transistors, so this schematic-listed file is effectively a datasheet. It likely gives pin order, ratings and package outline in condensed form. Use it to identify terminals before testing for shorts and to check that any replacement matches package and electrical limits shown.
