Gigabyte GA-P55A-UD3 schematic, apparently for revision 1.0B, supplied as a PDF in a 1.22 MB RAR archive.

Full-size 2.47 MB copy of the Quanta Usopp SLS schematic for the Acer Aspire T5000 desktop, offered in PDF form.

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.

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.

A 318 KB PDF covering the 2SK2882, listed under schematics but almost certainly a datasheet given the bare part number in its name.

The 2SK2792 part number appears here with an unexplained 1-5 suffix, possibly a page range or edition marker.

Short 34.8 KB datasheet-style PDF for the 2sk2576, an N-channel FET under the Japanese JIS 2SK designation.

The 2SK2545 is the subject of this 415 KB PDF, catalogued as a schematic but by its name a discrete transistor document.

Part-number PDF for the 2SK1471, 92.5 KB in size and labelled as a schematic in the index.

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…

The 2SJ511 named in this 417 KB PDF is a JIS-coded semiconductor, the 2SJ prefix signalling a P-channel field-effect transistor.

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.

PDF document, 39.0 KB, for a part named 2SC4627J, with an extra _E tag in the name whose meaning is not stated.

Catalogued as a schematic, this 184 KB PDF is named only after the part number 2SC5175, so it is most likely the manufacturer datasheet for that discrete transistor.

Brief 40.6 KB PDF for the 2SC4543, carrying an _E suffix whose meaning the name does not explain, and filed under schematics.

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

A 42.8 KB PDF for the 2SC5639, placed under schematics although its name is a bare part number pointing to a transistor datasheet.

Smallest of the batch at 30.8 KB, the PDF named 2SC5607 is presumably a concise datasheet for that NPN transistor despite being labelled a schematic.

A 51.7 KB PDF for the 2SC4208, with an _E suffix in the name whose meaning is not stated; it could mark an edition or language version, but that is unconfirmed.

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.

A 39.3 KB PDF for the 2SC5490 component, which belongs to the 2SC range of NPN bipolar transistors under Japanese JIS numbering.

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.

Datasheet PDF, 81.8 KB, for the 2SC3997 transistor, placed in the schematic listing. JIS numbering uses 2SC for NPN bipolar transistors; nothing else, such as maker or…

Brief datasheet-type PDF for the 2SC3920 at 30.5 KB, indexed under schematics. The file name contains only the part number.

The 2SC5416 base part is described in this 45.8 KB PDF, indexed as a schematic, with an LS variant held in a separate file.

Component document for the 2SC5000, a 179 KB PDF placed among schematics. The file name gives nothing besides the part number.

2SC3789 is the sole identifier on this 157 KB PDF, placed in the schematic section of the index.

The 2SC3502 NPN transistor is the subject of this 157 KB PDF, which the index files under schematics.

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

Component documentation for the 2SC3183 transistor, supplied as a 106 KB PDF and listed under schematics.

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.

Named after the 2SA1537 transistor, this 41.0 KB PDF sits in the schematic category but should contain the manufacturer data for that part.

A compact 37.5 KB PDF carrying the name 2SA2044, a Japanese JIS transistor number in which 2SA stands for a PNP bipolar type.

An 85.0 KB PDF covering the 2SA1965, whose 2SA prefix under JIS rules marks a PNP bipolar transistor.

Part documentation for the 2SA1932, supplied as a 197 KB PDF. The file is listed as a schematic, but the name holds only the component number, so treat it as a…

Small 27.6 KB PDF for the 2N7051, filed as a schematic but by its name a datasheet for one discrete semiconductor.

A compact 43.5 KB PDF filed under schematics and named for the 2N6547, a part number from the JEDEC 2N registration series for discrete semiconductors.
