Schematic in PDF for the Gigabyte GA-B150M-HD3 DDR3 motherboard, revision 1.0, packed in a 990 KB RAR; the WP tag in the name is unclear.

Boardview for the Gigabyte GA-H110-D3A desktop motherboard at revision 1.0, packed in a 754 KB RAR archive.

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…

Small 67.8 KB PDF for the 2SD1854, a part number in the Japanese 2SD series of NPN bipolar transistors, so it is really a datasheet rather than a full schematic.

Single PDF of 40.8 KB for the 2SD2216, listed as a schematic but most likely a component datasheet, since the name is a part number rather than a board.

A 29.2 KB PDF documenting the 2SD2639 part, catalogued as a schematic. Nothing beyond the type number is stated in the name.

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.

Labelled 2SD1997, this 86.1 KB PDF is indexed as a schematic, yet a bare transistor part number points to a manufacturer datasheet.

Datasheet-style PDF for the 2SD1423, 41.0 KB, stored as a schematic; the trailing _E in the name is not explained by the file itself.

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.

Reference sheet for the 3SK143, delivered as a 35.1 KB PDF and indexed under schematics. Beyond the part number the name says nothing.

Datasheet-style PDF for the 3LP02N, about 41.5 KB and listed as a schematic. No device, brand or board details appear in the name beyond the part code itself.

The 34.0 KB PDF named 2SK3557 is indexed as a schematic, but its name is a JIS component number, so it is almost certainly a datasheet.

Covering the 2SK2865, this 424 KB PDF sits in the schematic category but, judging by its name, is the component datasheet.

Here the 2SK2746 is documented in a 420 KB PDF, categorised as a schematic yet named like a single-part datasheet.

Reference sheet for the 2SK2599 in a 418 KB PDF, placed in the schematic section although the name holds nothing but the part number.

Compact 30.7 KB PDF for the 2SK2593, filed as a schematic though the lowercase name is simply a semiconductor part number.

Covering the 2sk2580, this 34.5 KB PDF is labelled a schematic yet identifies only a semiconductor part, pointing to a short datasheet.

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.

The 2SK2010 transistor is documented in this 90.1 KB PDF, filed among schematics but in substance a datasheet for an N-channel FET, as the JIS 2SK prefix indicates.

A 95.0 KB PDF named after the 2SK1908, listed in the schematic section of the index. Since 2SK is the Japanese registration prefix for N-channel FETs, treat it as the…

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

Listed as a schematic, this 125 KB PDF is named after the 2SK1466, a part code that under the Japanese JIS scheme denotes an N-channel field-effect transistor.

Component sheet for the 2SK1069, an N-channel FET from the Japanese 2SK numbering range, stored as a 98.7 KB PDF.

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.

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.

Small 43.1 KB PDF for the 2SJ400, likely a short datasheet despite being indexed as a schematic.

A 92.7 KB PDF catalogued under schematics but titled only 2SJ228, a JIS-style designation used for P-channel FETs.

PDF datasheet of about 56 KB for the 2SD661 transistor, with an _E suffix that probably indicates an English edition.

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…

A 39.6 KB PDF for the 2SC5216, with an _E tag in the name that is not explained. It is listed as a schematic, but the name points to a transistor datasheet.
