Boardview for the ASUS GL552JX gaming laptop mainboard, delivered as a 234 KB ZIP archive.

Small 67.8 KB PDF for the 2SD1854, a part number in the Japanese 2SD series of NPN bipolar transistors, so it is really a datasheet rather than a full schematic.

Part datasheet for 5HP01SP, a 27.5 KB PDF. The name carries no model, brand or board number, only the device code with an SP suffix that likely identifies its package.

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

For the 2SK2744 this 177 KB PDF provides component-level reference material, although the index lists it among schematics.

Compact 30.7 KB PDF for the 2SK2593, filed as a schematic though the lowercase name is simply a semiconductor part number.

Short PDF of 23.2 KB named for the 2SK2324 part. In JIS nomenclature 2SK denotes an N-channel FET, so this schematic-labelled file is presumably a brief datasheet.

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.

Datasheet-style PDF of 105 pages' worth of nothing more than a part number: the 2SJ420, a device whose 2SJ prefix under Japanese JIS designation identifies a P-channel…

PDF document for the 2SJ346, filed in the index as a schematic but named after a discrete semiconductor part.

Catalogued as a schematic, this 88.5 KB PDF is named only 2SJ230, a JIS code in which the 2SJ prefix identifies a P-channel field-effect transistor.

An 82.4 KB PDF bearing only the part number 2SJ188; the 2SJ prefix in Japanese numbering denotes a P-channel field-effect transistor, so this is likely its datasheet…

Small 788 KB RAR archive for the OPPO R9 smartphone. The name states only the model, and the contents, likely a handful of schematic or layout pages given the size, have…

Base-version document for the 2SC4738, a 236 KB PDF placed in the schematic category. Following the JIS scheme, the 2SC prefix denotes an NPN bipolar transistor; F and…

Reference sheet for the 2SC4627, a JIS-numbered NPN transistor, supplied as a 61 KB PDF.

The 2SC5171 named in this 169 KB PDF is a JIS-style part number, where the 2SC prefix denotes an NPN bipolar transistor for high-frequency applications, so the content…

Datasheet-style PDF of 119 KB for the 2SC4401, listed in the index under schematics although the name points to a single semiconductor part.

Catalogued as a schematic, this 45.8 KB PDF is named after the 2SC5503, a part number in the Japanese 2SC series used for NPN bipolar transistors.

Catalogued as a schematic, this 100 KB PDF is named after the 2SC4031 and is most likely its datasheet. JIS numbering uses 2SC for NPN bipolar transistors.

Labelled 2SC4835 with an _E suffix, this 41.5 KB PDF is filed as a schematic but refers to a JIS-numbered NPN transistor, indicated by the 2SC prefix.

Datasheet PDF of 172 KB carrying the part number 2SC5358, listed under schematics in the index.

A 97.4 KB PDF for the 2SC3151, an NPN bipolar transistor according to its JIS 2SC designation.

Reference document for the 2SC3112 transistor, supplied as a 257 KB PDF and filed under schematics. The name holds only the part number.

An 84.6 KB PDF for the 2SC3071, filed as a schematic. The name supplies nothing beyond the part number, so this is probably a compact datasheet.

Reference document for the 2SC1815, a 310 KB PDF classed as a schematic. In JIS numbering the 2SC prefix denotes an NPN bipolar transistor, and the file is most likely…

Very small PDF of 26.3 KB named with the part number 2N5639 and nothing else. Listed as a schematic, it is most plausibly a short datasheet, since 2N codes are JEDEC…

Component datasheet for the 2N5366, a 60.8 KB PDF filed in the schematic category. The name gives only the part number, with no manufacturer, package or revision…

Datasheet for the 2N5209 transistor, a 278 KB PDF with an RE suffix that is not explained by the name.

PDF of 86.6 KB for the 2N4036, with an r0 tag in the name that likely marks a revision zero edition, though the file does not say so explicitly.

Only the number 1SS358 appears in the name of this 50.5 KB PDF, pointing to a data sheet for a small-signal silicon diode under the JIS 1SS prefix, despite its schematic…

A 21.1 KB PDF carrying the part number 1n6768, best understood as a datasheet for a JEDEC 1N-series device rather than a board schematic.
