Only the part number 2SC4563 identifies this 85.4 KB PDF, categorised as a schematic but best treated as a datasheet for a JIS-designated NPN bipolar transistor of the high-frequency group. Package and manufacturer are not stated. Open it in any PDF viewer to look up terminal layout, voltage and current limits and electrical characteristics. That information supports in-circuit diode testing and selection of replacements; confirm the component marking and package match the drawings before ordering parts.
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.
