Schematic in PDF form for the ASUS S300CA notebook, with no board revision stated in the name.

Schematic set for the Nokia N72 Symbian phone in a 1.79 MB PDF. The file name names only the model; no board number or revision is provided, so check the main board…

Nokia 6500 schematic in PDF format, 420 KB; the name does not specify whether it covers the 6500 classic or the 6500 slide, so check the board against the drawings…

Short repair guide for the ASUS K52JT, a 209 KB PDF catalogued with schematics. ASUS repair guides usually contain block diagrams, power sequence, main voltage rails and…

A small 28.8 KB PDF from the GT-S7580 and GT-S7582 service document set, numbered section 11 and tagged EPLIS, which likely stands for an electrical parts list.

PDF for the IRF540 MOSFET, and the name indicates the datasheet comes from Philips. Although listed under schematics, the 91.6 KB file is a component sheet with ratings…

A 41 KB PDF covering the part coded 5HN02SP, listed with schematics but naming only a component. SP is most likely the package designation in the 5HN02 series.

Reference sheet of 41.7 KB in PDF format for the 3LP02M, filed among schematics though it is effectively a component datasheet.

PDF document, 28.7 KB, labelled as a schematic and named 3LP01SP. The name points to an individual semiconductor part code with an SP suffix and gives no device, brand…

Named 2SD2426, this 69.1 KB PDF is filed as a schematic, though the 2SD prefix follows the Japanese JIS code for NPN bipolar transistors and points to a single-part…

File name 2sk198 is a JIS semiconductor number, so this 31.8 KB PDF, though catalogued as a schematic, is best treated as a brief component datasheet.

The 2sk2790 name on this tiny 21.3 KB PDF is the only information provided. Filed as a schematic, it most probably holds a brief datasheet for an N-channel field-effect…

A PDF of about 88 KB for the 2SK2154, filed under schematics but most likely a component datasheet, since the name is just the part number.

Compact 79.7 KB PDF for the 2SJ413, indexed under schematics but by its number a single-component datasheet.

Here is a 42.3 KB PDF for the 2SC5264LS, indexed as a schematic. JIS numbering makes the 2SC prefix an NPN bipolar transistor, and the LS letters identify a variant of…

A 161 KB PDF carrying only the part number 2SC4650, a JIS-registered NPN transistor. Nothing in the name links it to a specific device, so treat it as a component…

Despite sitting in the schematic category, this 99.9 KB PDF is named after the 2SC4164 and should therefore contain transistor specifications rather than a circuit…

Filed as a schematic, this 52.8 KB PDF covers the 2SB709A, a PNP bipolar transistor in JIS terms, with the A suffix indicating a variant of the 2SB709 that may carry…

Indexed as a schematic, this 40.2 KB PDF is named 2SB1220 with an _E suffix and almost certainly contains the datasheet for that JIS transistor.

Small 21.4 KB PDF for the 2SA733 PNP transistor, with the UTC tag in the name pointing to the Unisonic Technologies version of this widely used general-purpose part.

Datasheet-style PDF, 206 KB, for the 2SA1893 PNP transistor from the JIS 2SA family. Nothing in the name points to a specific device or board, so treat it as part…

Specifications for the 2SA1873 PNP transistor, provided as a 247 KB PDF. The 2SA prefix comes from the JIS semiconductor naming system and denotes a PNP bipolar part, so…

At 320 KB, this PDF for the 2SA1163 is the largest of this group of 2SA files and likely a full manufacturer datasheet with characteristic curves.

Specification document for the 2SA1728, provided as a 91.2 KB PDF with no board or device model in its name.

The 2SA1703 is covered by this 126 KB PDF, listed in the schematic category although only the part number appears in the name.

A 53.4 KB PDF for 2N5551, carrying a Sam tag in brackets that likely names the publishing manufacturer, though the abbreviation is not spelled out.

A 58.4 KB PDF that covers two JEDEC part numbers together, the 2N5088 and 2N5089, with a Sam tag in brackets whose source is not spelled out in the name.

Indexed as a schematic, 1T369 is a 44.8 KB PDF identified only by its part code. No device, brand or board revision is stated in the name.

A 57.0 KB PDF listed as a schematic and named 1SV216, followed by an underscore that appears to be a naming leftover.

A 69.5 KB PDF titled with the component number 1SS367, with nothing in the name about a device or board.

Only the component code 1SS294 appears in this 69.1 KB PDF name, so it cannot be tied to any specific board or laptop.
