Datasheet-type PDF for the 2SK2740, 138 KB, with a 1-5 suffix in the name whose meaning is not stated, possibly an edition or page range.

PDF of 137 KB for the 2SK2713, carrying a 1-5 suffix of unstated meaning, likely an edition or page marker rather than a different device.

PDF document for the 2SK2374 part, filed under schematics but named after a Japanese-registered semiconductor rather than a board.

The 2SK1839 is covered in this 84.9 KB PDF, filed under schematics though the name points to a single semiconductor part.
