At 511 KB, the largest in this run of files, a PDF referenced by the transistor number 2SC2714 and filed as a schematic. JIS 2SC numbering denotes an NPN bipolar device, so this is probably the full datasheet with curves and tables. The name carries no further details. Use it during repair to confirm pinout, hFE classification and absolute maximum ratings before replacement. Compare marking codes on the part itself, since small packages often carry abbreviated codes rather than the full number.
