A 255 KB PDF for the 2N4918, tagged RE in the name, possibly a revised or alternate edition though this is not defined.

Plain-named 2N3905 document in PDF format, 62.6 KB, catalogued with schematics but most likely a one-part datasheet.

A 148 KB PDF named 27lc512, filed under schematics but most likely a datasheet for a low-voltage 27-series EPROM, given how the part number is built.

MSI MS-AA711 schematic, version 2.2, delivered as a 1.28 MB PDF and apparently the latest of the three versions listed for this board number.

Sharing its 173 KB size with a neighbouring entry, this PDF is named 2SA1986, the JIS number of a PNP bipolar transistor.

Dell 11th Gen laptop schematic in PDF form for board 203070-1, a numbering pattern used by the ODM Wistron for Dell motherboards.

A 100 KB PDF whose name is simply the part number 2SC4171; despite the schematic label it is best treated as a transistor datasheet.

Documentation for the 2SC5304 transistor, stored as a 36.3 KB PDF and indexed in the schematic category.

Component reference for the 2SD2635, a 35.2 KB PDF listed among schematics. The file name offers only the part number, with no manufacturer or revision given.

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

Datasheet-type PDF for the 2SD1878, 90.6 KB, placed in the schematic category of the index. The name contains nothing beyond the part number.

Datasheet-style PDF for the 2SK1117, with the name noting NTE2379 as its equivalent, meaning the NTE replacement line lists that part as a cross-reference.

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…

Named only after the part 2SC4363, this 88 KB PDF is catalogued as a schematic but is most likely the manufacturer datasheet for that transistor.

At 249 KB this PDF is the largest in the group and covers the 2SA1618, indexed as a schematic but in practice a transistor reference.

PDF reference sheet, 214 KB, for the 2N6282 discrete device, listed as a schematic but most likely a datasheet.

Part number 2N5770 is the only detail this 296 KB PDF carries. It is listed as a schematic but names no board or laptop model.

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 documentation in PDF form, 203 KB, covering the 24C08 and 24C16 I2C serial EEPROMs.

Schematic for an X421EA mainboard at revision 2.1, provided as a 10 MB PDF. The name states no brand, but X421EA matches ASUS VivoBook model naming; verify against the…

MSI MS-7392 schematic labelled R1.2, delivered as a PDF in a RAR archive. The pages let a repairer follow every power rail, see which controller drives each phase and…

Laptop schematic labelled Z94RP, revision 1.2, supplied as a 2.50 MB PDF. The name gives no brand or board number beyond this project code, so confirm the details on the…
