Sized at 316 KB, this PDF covers the 2SC5422, a part number in the Japanese JIS series used for NPN bipolar transistors. Although catalogued as a schematic, it should be a component datasheet. No further specifics are given in the name. The sheet helps when diagnosing a shorted or open transistor: it shows which leg is collector, base and emitter and lists limits to respect when selecting a substitute. Match the body marking and package before relying on it.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @cyberlanelectonik. Enginerys does not host this file.
