At 249 KB this PDF is the largest in the group and covers the 2SA1618, indexed as a schematic but in practice a transistor reference.

The 2SA1592 is covered by this 156 KB PDF, filed as a schematic although the name refers to a single semiconductor.

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

Part reference for the 2SA1291 in PDF form, 40.8 KB. Filed as a schematic, but the name holds nothing other than a component code, and 2SA under the Japanese JIS scheme…

Datasheet-type PDF, 180 KB, for the 2SA1899 component, filed as a schematic although the name carries no detail besides the part number.

Datasheet PDF of 42.2 KB for the 2SA1883, identified only by its part number. Japanese JIS numbering uses 2SA for PNP bipolar transistors, so the content describes a…

Component sheet for the 2SA1866 PNP bipolar transistor, stored as a 55.4 KB PDF. The 2SA prefix follows Japanese JIS conventions for PNP devices.

A 207 KB PDF for the 2SA1736, filed in the index as a schematic but named after a single semiconductor part rather than a board.

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.

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.

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

A 126 KB PDF filed under schematics, though its name, 1SS269, points to a semiconductor part rather than a circuit board.

PDF schematic of roughly 64 KB for a function daughterboard of the X63C project, a Quanta code associated with the HP ProBook 450 G3 elsewhere in this collection; no…

Schematic for a Dell laptop board with the Compal number LA-7731P, as a 3.14 MB PDF; the exact Dell model is not named.

Small 31 KB PDF schematic of an IO board for a project code-named Michigan, version A01 with a 0312 tag, probably a date.

Circuit diagram for the HP DM1, project name Flex, board H210UA1, revision C, based on the AMD Brazos platform with the code name Garbo also in the title.

ASUS Eee PC 1015P netbook schematic, a 518 KB PDF whose name marks it as an unlocked copy, meaning restrictions such as printing or text search have been removed.

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

Small 57.3 KB PDF for the 2SC5060, filed under schematics though the name suggests a transistor part sheet.

Part sheet in PDF form, 29.1 KB, for the 2SD2646 transistor, filed in the schematic category. The name supplies only the type number, without brand or revision.

Small PDF of 92.1 KB filed under schematics, though its name is simply the part number 2SD1998, so it is almost certainly a component datasheet rather than a board…

A 115 KB PDF named after the 2SD1625 part number, catalogued as a schematic but in practice most likely the transistor's datasheet.

PDF covering the 3SK189, about 178 KB in size and listed in the schematic category, though the name points to a single component datasheet.

A 111 KB PDF for the 2SD2281, which under the Japanese JIS system is an NPN transistor from the low-frequency 2SD series.

A 166 KB PDF for the 2SD1904 transistor, listed here as a schematic but by its name almost certainly the manufacturer data sheet.

Small 45.6 KB PDF named 2SD1902, a Japanese standard transistor number; despite the schematic label it is most probably a short datasheet.

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

A compact 106 KB PDF covering the 2SK2919 transistor, indexed as a schematic though the name points to a manufacturer datasheet.

PDF documentation, 431 KB, for the 2SK2883 N-channel FET, placed in the schematic section of the catalogue.

Part reference for the 2SK2862 in a 411 KB PDF, listed under schematics in this index. The name carries only the transistor number.

A compact 134 KB PDF titled with the part number 2SK2839 and catalogued as a schematic.

Datasheet-style PDF of 21.4 KB for the 2SK2751, listed under the schematic category. The 2SK designation belongs to the Japanese JIS system and marks an N-channel…

Component document for the 2SK2745 in PDF form, 399 KB, filed as a schematic. Because 2SK is the Japanese JIS prefix for N-channel field-effect transistors, the file…

PDF of 137 KB for the 2SK2713, carrying a 1-5 suffix of unstated meaning, likely an edition or page marker rather than a different device.

PDF document for the 2SK2374 part, filed under schematics but named after a Japanese-registered semiconductor rather than a board.
