At 242 KB, the 2SD2092 PDF is one of the larger files in this series and carries no information beyond the part number.

Covering the 2SD2067, this 60 KB PDF carries an E suffix that the name leaves unexplained.

Catalogued as a schematic, the 400 KB PDF is named only for the 2SK2835 part number. In the JIS scheme the 2SK prefix denotes an N-channel field-effect transistor, which…

The 2SK2101 part number is followed by an extra 01mr suffix in this 175 KB PDF. The name does not explain that suffix, which could be a document code or revision.

A 166 KB PDF covering the 2SK1961 transistor. The 2SK series in the JIS system denotes N-channel FETs, so this schematic-categorised file should be read as a component…

PDF of 98.9 KB for the 2SK1898, listed under schematics but in practice a component reference for one transistor.

PDF reference, 105 KB, for the 2SK1813 transistor. In the Japanese JIS scheme, 2SK designates an N-channel field-effect transistor, so this is probably its datasheet.

PDF for the 2SC5584 transistor, only 45.9 KB, catalogued under schematics. The name holds nothing beyond the part number, so manufacturer and revision are not given.

Short 30.6 KB PDF covering the 2SC5763, filed under schematics. No laptop, board or revision appears in the name, only the part designation, which in the Japanese system…

At 411 KB, this PDF for the 2SC5717 is one of the larger documents in the set and is probably a complete datasheet with graphs.

Just under 100 KB, this PDF is identified only as 2SC3448 and catalogued as a schematic.

PDF reference for the 2SA1360 transistor, roughly 176 KB. The file is labelled a schematic, but naming it after one part points strongly to a datasheet.

A 137 KB PDF on the 2SA1225, named only with the part number; despite the schematic category it is most likely the manufacturer datasheet.

Compact 45.3 KB PDF for the 2SA1207, listed as a schematic, though the name offers only the part number, which suggests a datasheet.

Quanta schematic for a project coded ZN5, in PDF format. The name gives neither the laptop brand nor the model, so identify the target machine by finding the ZN5 code on…
