The 2SD2598 transistor is covered in this 59.3 KB PDF, whose name ends in an _E suffix.

The 5LN02N part is covered by this 41.5 KB PDF, indexed as a schematic but most likely a component datasheet.

Filed as a schematic, this 53 KB PDF is named after the 2SD1725 part number, so it is most likely a component datasheet rather than a board diagram.

Reference PDF for the 3N255, sized at 42.2 KB and catalogued among schematics, though nothing beyond the part number is given in the name.

Named 2SD2426, this 69.1 KB PDF is filed as a schematic, though the 2SD prefix follows the Japanese JIS code for NPN bipolar transistors and points to a single-part…

Component reference for the 2SD1993, a 45.5 KB PDF listed among schematics. Following Japanese JIS part numbering, 2SD identifies an NPN bipolar transistor of the…

Datasheet PDF, 43.0 KB, for the 2SD2321, with an _E suffix carried over from the original name, though the suffix itself is not explained.

The file, a 28.4 KB PDF, is named 2SK3485 and catalogued as a schematic; the name is a JIS semiconductor number, so treat it as a short datasheet.

Part documentation for the 2SK2914 in PDF form, 396 KB, placed in the schematic section of the index.

Covering the 2SK2865, this 424 KB PDF sits in the schematic category but, judging by its name, is the component datasheet.

PDF of 410 KB for the 2SK2717, recorded as a schematic but named after a single semiconductor part.

Part reference for the 2SK2607, an N-channel FET according to the 2SK prefix of the JIS numbering convention.

Datasheet in a 33.2 KB PDF for the 2SK1967, a Japanese-registered N-channel field-effect transistor indicated by the 2SK prefix.

The 2SK1449 gives this 109 KB PDF its name, and nothing else is stated. It is filed as a schematic, though it is probably the device data sheet.

The 2SK1375 N-channel field-effect transistor is covered by this 150 KB PDF, filed under schematics in the catalogue.

Component sheet for the 2SK1069, an N-channel FET from the Japanese 2SK numbering range, stored as a 98.7 KB PDF.

A PDF filed under schematics but named after the 2SK404, a part number in the Japanese JIS semiconductor scheme, where the 2SK prefix marks an N-channel field-effect…

Catalogued among schematics, the 43.5 KB PDF called 2SJ499's neighbour 2SJ485 refers to a semiconductor part; under the JIS scheme the 2SJ prefix designates a P-channel…

Small 43.1 KB PDF for the 2SJ400, likely a short datasheet despite being indexed as a schematic.

A 92.7 KB PDF catalogued under schematics but titled only 2SJ228, a JIS-style designation used for P-channel FETs.
