F83VF motherboard schematic, revision 1.1 according to the r11 marking in the file name, delivered as a 1004 KB PDF.

Schematic for the Toshiba Satellite A135-S2686, built by Compal; the name ends at the LA prefix and does not give the full board number.

ASUS repair guide for the K43SV notebook in a 630 KB PDF, filed in the schematic category.

A PDF reference sheet for the 2SD2259 transistor, catalogued as a schematic but in practice a component datasheet of 43.3 KB.

Small 39.9 KB PDF for the 2SD2474, carrying an _E suffix whose meaning the name does not state; it may reflect a language or edition marker.

Component documentation for the 2SK2920, a 409 KB PDF filed under schematics in this index but almost certainly a part datasheet.

A 365 KB PDF for the 2SK2859, filed under the schematic type though it is most probably a manufacturer datasheet. Nothing other than the part number appears in the name.

Datasheet-type PDF for the 2SK2740, 138 KB, with a 1-5 suffix in the name whose meaning is not stated, possibly an edition or page range.

Short datasheet-type PDF of 30.0 KB for the 2sk2588, an N-channel FET according to the JIS 2SK prefix.

Small 30.0 KB PDF covering the 2SK2047 transistor. Under the JIS naming system the 2SK prefix marks an N-channel FET, so this is best treated as a part datasheet rather…

The 2SK1839 is covered in this 84.9 KB PDF, filed under schematics though the name points to a single semiconductor part.

A 291 KB PDF dedicated to the 2SK1830. The 2SK code is the Japanese JIS designation for N-channel field-effect transistors, so this is almost certainly a datasheet…

An 88.5 KB PDF on the 2SK1738 transistor. In the JIS system, 2SK designates an N-channel FET, so this file is most likely the datasheet rather than a circuit schematic.

The 2SK1489 named here is a discrete transistor code: under JIS numbering, 2SK denotes an N-channel field-effect transistor.

Reference PDF for the 2SK1457, filed under schematics and 122 KB in size. The file name carries only the part number.

The 2SK1456 is the only information in the name of this 124 KB PDF, which is indexed as a schematic.

Datasheet document for the 2SK1103 transistor, filed as a 29.5 KB PDF. Parts beginning with 2SK are N-channel field-effect transistors registered under the JIS scheme…

For the 2SK664 transistor, this 34.9 KB PDF is indexed as a schematic but, judging by the JIS 2SK naming used for N-channel field-effect transistors, it is a datasheet…

Data for the 2SJ608 in a lightweight 27.9 KB PDF, indexed as a schematic. Under the Japanese JIS scheme the 2SJ prefix denotes a P-channel FET, so this is likely a…

Catalogued as a schematic, this 361 KB PDF carries only the part number 2SJ567 in its name.

Filed under schematics, the 143 KB PDF named 2SJ509 most probably holds the datasheet for a single transistor, since 2SJ in the Japanese JIS scheme designates a…

Nothing beyond the code 2SJ272 is given in the name of this 92.3 KB PDF. Japanese JIS numbering assigns the 2SJ prefix to P-channel field-effect transistors, so the…

The 2SD1294 is the only detail this 209 KB PDF name provides; the file is filed as a schematic but corresponds to a transistor part number.

Specification PDF, roughly 32 KB, for the 2SD667 transistor, listed among schematics but in fact a component datasheet.

Small 46.2 KB PDF for the 2SC5501. Under the Japanese JIS scheme, a 2SC prefix marks an NPN transistor intended for high-frequency use.

Datasheet PDF for the 2SC3931, 60.7 KB, with the _E suffix common to this group of files and listed as a schematic.

Component document for the 2SC4809 transistor, filed under schematics but by its name and small size most likely a manufacturer datasheet.

Datasheet-type PDF for the 2SC4787, a JIS-numbered NPN transistor, filed in the schematic category.

Short 108 KB PDF datasheet for the 2SC3601, placed in the schematic section of the index.

PDF document named after the 2SC5332 part number, filed here under schematics but most likely a component datasheet rather than a board diagram.

A 41.1 KB PDF titled with the part number 2SC1980 and an _E suffix, catalogued among schematics.

Part documentation for the 2SB1287 in a 63.5 KB PDF; the 1-2 in the name probably marks pages one and two of the sheet. No device or board details are included.

PDF document of 196 KB identified only by the part number 2SA2058. Under the Japanese JIS convention, 2SA parts are PNP bipolar transistors, so this is almost certainly…

Datasheet-style PDF for the 2SA1241, 279 KB in size and filed among schematics. Nothing else is given in the name, so expect the usual electrical characteristics rather…

Small 41.8 KB PDF for the 2SA1890, with an _E suffix in the name that commonly marks an English-language edition of a Japanese datasheet, though the file does not…

Datasheet-style PDF for the 2SA1858 semiconductor, catalogued here under schematics, with an _E suffix in the name that likely marks an alternate edition of the…
