PDF document for the 2SK715 part number, catalogued under schematics but almost certainly a component datasheet, since the 2SK prefix follows the Japanese JIS…

Compact 29.9 KB PDF titled with the part number 2sk301 only. The 2SK prefix under JIS rules marks an N-channel FET, so this is best treated as a component data sheet…

Stored under schematics, this 122 KB PDF is named for the 2SJ195, a P-channel FET in the Japanese JIS numbering system, and is most likely its datasheet.

PDF document of 171 KB for the 2SD1314, indexed as a schematic although the part number points to a component datasheet rather than a board drawing.

Datasheet-type PDF for the 2SD1145 transistor, 89.8 KB, placed in the schematic category of the index.

Here is a 37.0 KB PDF for the 2SD1030, named with an _E suffix that is not explained in the file name.
