Schematic for the Acer Swift 3 SF314-41 laptop, Strongbow_PK board 18848-1, provided as a PDF in a 4.22 MB RAR archive; the name notes it opens in SumatraPDF.

A 43.4 KB PDF datasheet covering the 1N5400 diode. Although catalogued as a schematic, it is a part specification sheet, the kind of reference you open when a rectifier…

An 86.9 KB PDF identified by the part number 2SJ231 alone. Under Japanese JIS designation, 2SJ covers P-channel FETs, so this is most plausibly a transistor datasheet…

A 153 KB schematic-category PDF whose name, 60HFU, states no brand, product or board revision.

Schematic PDF with a short name showing only JV50, a MV tag, -1 and 0109, which is likely a project code with a revision and date, though the brand and model are not…

The 2SD1622 PDF, 138 KB in size, sits among schematics, but a file named only by a semiconductor part number is very likely the device datasheet.

A 94.8 KB PDF documenting the 2SD895, indexed as a schematic though the name names a single transistor.

Datasheet PDF, 170 KB, for the semiconductor numbered 2SC2705, placed in the schematic listing. Under JIS naming, the 2SC prefix marks an NPN transistor.

Named only 1SS301, this 67.0 KB PDF offers no device, board or revision information. The prefix follows the Japanese JIS designation for small-signal diodes, a family…

A 169 KB PDF carrying only the part number 2SC5319, which by the JIS system identifies an NPN bipolar transistor.

Component documentation for the 2N7222, a 227 KB PDF filed under schematics; the 2N prefix indicates a registered discrete semiconductor, so expect a datasheet rather…

Laptop schematic in PDF for the HP ProBook 4540s. The name does not give the ODM board number or revision, so open the title block and compare it with the code printed…

Schematic PDF of 1.87 MB named only SE, which most likely refers to the iPhone SE, though the name does not confirm the brand or generation.

A 386 KB PDF covering capacitors and inductors, filed as a schematic but by its name an educational reference rather than a device diagram.

Schematic PDF for the Lenovo IdeaPad Z500, 1.43 MB in size. The name gives no board number or revision, so open the document and compare its title block with the…

Compact 42.8 KB PDF for the 2SD2537, listed as a schematic though the name points to a single-component datasheet.

Transistor datasheet in PDF form, 188 KB, named 2SC5352 without any device or board reference.

Indexed under schematics, this 77.1 KB PDF is titled 1SV242 with a trailing underscore, and that is all the name reveals.

An 88.9 KB PDF indexed under schematics, named 61ctq045. The name gives no brand, model, board number or revision, so the subject must be confirmed by opening it.

Apple iPhone SE document in a 919 KB PDF whose Russian name means resistance measurement, so it most likely lists diode-mode or resistance readings for lines on the…

A 477 KB PDF for the 2SC5087 part, an NPN bipolar transistor by its Japanese 2SC designation.

At 98.9 KB, this PDF is named after the device 1SS364, indexed under schematics but most probably a diode data sheet.

The part number 2SC4473 is the only information in this 122 KB PDF name, and it identifies a Japanese JIS-coded NPN transistor of the high-frequency type.

A 128 KB PDF identified solely by the transistor number 2SC4218. JEITA naming assigns 2SC to NPN bipolar transistors, so despite the schematic label this is most…

Disassembly and reassembly guide in PDF form, 1.11 MB, with no device or brand named in the file name.
