Short 37.3 KB PDF for the 2SK544, a part number belonging to the JIS 2SK series of N-channel FETs; although indexed as a schematic, it should be a component datasheet.

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

Small 89.2 KB PDF labelled 2SJ191, a JIS designation that marks a P-channel FET, so the file is presumably that part's datasheet rather than a board schematic.

Bearing only the part number 2SC4393, this 319 KB PDF is indexed as a schematic yet is most likely the transistor datasheet.

Datasheet PDF for the 2SC5537 transistor, 32.5 KB, catalogued with schematics. In the JIS scheme 2SC denotes an NPN bipolar part, so this is component data rather than a…

Filed under schematics, the 2SC3993 PDF (107 KB) is far more likely a component datasheet, since the name is simply a JIS transistor part number.

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

PDF component sheet for the 2SC3481, 131 KB in size and catalogued with schematics. The file name holds just the part number; the 2SC prefix is the JIS designation for…

Covering the 2SC5353, this 208 KB PDF sits in the schematic category but, judging by the name, documents a single transistor.

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.

The 2SA1315 PNP transistor, per the Japanese JIS 2SA prefix, is the subject of this 220 KB PDF.

Datasheet for the 2N7053 in a 314 KB PDF, categorized with schematics. The size matches that of the 2N7052 file and both may come from a shared family document, though…

Indexed under schematics, this 26.9 KB PDF is labelled 2N6518, a JEDEC-registered discrete semiconductor designation.

This PDF of 178 KB sits in the schematic category and bears the number 2N6436 plus an RE suffix not explained by the name.

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…

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, this 63.9 KB PDF carries the name 1SV265 and nothing else. Under Japanese 1S numbering, the 1SV prefix denotes a Toshiba variable-capacitance…

Covering the 1SS394, this 66.2 KB PDF is filed as a schematic but most likely holds a component datasheet, since 1SS denotes Japanese-registered small-signal silicon…

The 1SS392 is documented in this 69.6 KB PDF, categorised as a schematic. Because 1SS is the Japanese numbering for small-signal silicon diodes, the file is most likely…

PDF file for the 1SS388 part, 68.6 KB, catalogued under schematics though most likely a single-component datasheet.

A compact 50.1 KB PDF named 1SS375, indexed under schematics but almost certainly a data sheet for one component.

Indexed as a schematic, this 68.4 KB PDF takes its name from the diode number 1SS372 and gives no device, board or brand information.

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

No device or board appears in the name 161cmq, which instead looks like a dual Schottky rectifier family code; at 47.0 KB this PDF is probably a short datasheet, though…

A 108 KB PDF listed as a schematic and titled 1SR124-400A, a code in the style of a discrete semiconductor part number, with the 400A suffix identifying a specific…

An 88.8 KB PDF labelled as a schematic with the code 70mt160p. Nothing in the name identifies a laptop, board maker or revision, so the document has to be opened to…

Named only 50WQ10F, this compact 39.2 KB PDF sits in the schematic category but gives no laptop model, brand or board number.

A 206 KB PDF filed as a schematic and identified only by the code 50RIA, with no laptop model, brand or board revision.

This 55.9 KB PDF, labelled 30CPQ050, carries a part-number style title rather than a motherboard number, indicating a component datasheet in the schematic category.

Circuit diagram in PDF form for the X55C, with an additional RG suffix whose meaning the name does not explain. The file is 1.39 MB and opens in any PDF viewer.

PDF schematic of 852 KB named only ME4812, which gives no clear indication of the brand, device or board revision it covers.

PDF schematic, 1.07 MB, for the Sony VAIO motherboard MBX-194, paired in the name with the project code M780, which likely belongs to the ODM that built the board.

Compal LA-D841P schematic in PDF, compressed into a 2.86 MB RAR; the name gives no brand, model or revision.

Zipped schematic for the Compal LA-A481P notebook board, 1002 KB, which the name says contains a PDF. No brand, model or revision is given.

PDF schematic whose name, KL2D, is only a short project or board code, with no brand, revision or model given.

Schematic in PDF for the ASUS K53SV notebook; the name does not state the mainboard revision.

PDF schematic for the Apple logic board 820-3023, packed into a 1.42 MB RAR archive. The name carries no revision letter, so confirm the suffix on the board before…

Schematic for the Apple logic board 820-2997, provided as a PDF compressed in an 841 KB RAR archive.

Decrypted schematic in PDF for MSI board V328, the _90 suffix pointing to revision 9.0, with the number 00017967 included in the name.

MSI MS-7C58 schematic marked revision 10, likely meaning 1.0, with reference number 00205363 in the name, provided as a PDF inside a 1.80 MB RAR.
