Component documentation for the 4N38 optocoupler, filed under schematics though it is in practice a part datasheet in PDF form of about 140 KB.

Small 33.0 KB PDF for the 3SK144, catalogued as a schematic but named for an individual semiconductor, so it is most likely a datasheet.

Reference sheet for the 3SK180 semiconductor in PDF form, roughly 173 KB, catalogued as a schematic.

Datasheet-type PDF of 31.1 KB for the 2SK3412 semiconductor, stored under the schematic category.

PDF reference for the 2SK2825, 301 KB in size and listed in the schematic section. The 2SK designation, from the Japanese JIS numbering system, belongs to N-channel…

Part reference for the 2SK2782, delivered as a 419 KB PDF under the schematic label. The 2SK prefix follows Japanese JIS numbering for N-channel field-effect…

Filed under schematics, this 138 KB PDF is named after the 2SK2463, a JIS-style part number, so it is most likely a component datasheet rather than a board drawing.

A 398 KB PDF for the 2SK2034, a part in the Japanese 2SK series of N-channel field-effect transistors.

The 2SK1826 datasheet in PDF form, sized 320 KB and filed as a schematic. Japanese JIS designations starting with 2SK identify N-channel field-effect transistors.

Small 35.2 KB PDF identified only by the part number 2SK665, a designation from the Japanese 2SK family of N-channel FETs, so the content is most likely a component…

For the 2SJ579, this 42.7 KB PDF is indexed as a schematic, but a bare part-number name typically marks a datasheet.

Reference PDF for the 2SD973, 53.5 KB, with an _E suffix the name leaves undefined. It sits in the schematic category, but the JIS 2SD prefix marks an NPN transistor for…

Component reference for the 2SC3963, supplied as a 193 KB PDF in the schematic category.

For the 2SC5315, a JIS-coded NPN bipolar transistor, this 126 KB PDF is indexed as a schematic but most probably holds the component datasheet.

At 179 KB, this PDF for the 2SB1495 is one of the larger documents in the set and likely includes graphs alongside rating tables.

PDF reference for the 2SA1574 transistor, 47.9 KB in size. Apart from the part number, the name says nothing about package, maker or revision.

Filed as a schematic, this 40.6 KB PDF takes its name from the 2SB1207 part number, followed by an _E suffix, and most likely contains the transistor datasheet.

Indexed as a schematic, this 72.3 KB PDF relates to the 2SB888, likely as its data sheet.

A 119 KB PDF carrying component data for the 2SA1404, filed as a schematic in the index. Japanese JIS numbering assigns the 2SA prefix to high-frequency PNP transistors.

PDF document for the 2SA1380, a part number that follows the Japanese JIS scheme, where the 2SA prefix marks a PNP transistor intended for high-frequency use.

PDF of about 151 KB referencing the 2SA1353 transistor. It is filed as a schematic, but the bare part-number name indicates a component datasheet.

Only the JEDEC part number 2N5460 is given for this 115 KB PDF, listed as a schematic. The same size as the 2N5461 and 2N5462 files suggests a shared family datasheet…

PDF of 97.8 KB for the 40EPF-HV, filed as a schematic though it is component documentation.

PDF circuit diagram, 837 KB, for the Compal LA-5752P board, marked with a (1) copy suffix and probably the same as the other LA-5752P files.

Schematic PDF for Quanta board DA0BLKMB6E0, project BLK as the OBLK suffix suggests. The name gives no laptop brand or model, only the Quanta board code, so identify the…

Power sequence diagram for Apple logic board 820-01598, labelled J213 and X1536, a compact 85.9 KB PDF.

First-revision schematic, Rev 1.0, for the MSI MS-V277 board, in PDF form inside a RAR archive slightly larger than the later versions.

Circuit diagram in PDF form for the MS-7395 board, revision 0A, around 1.15 MB. The number follows the MS-7xxx style MSI uses for its desktop mainboards, though the…
