PDF of about 99 KB for the 2SC4770, filed under schematics though the name points to a transistor datasheet rather than a board diagram.

Covering the 2SC4612, this 155 KB PDF is indexed as a schematic but is in practice a transistor datasheet, as only the part number appears in the name.

The 86.7 KB PDF named 2SC4572 is filed as a schematic yet carries a transistor part number, so expect a component datasheet rather than a circuit diagram.

Transistor datasheet in PDF for the 2SC4247, 302 KB, indexed with schematics rather than board diagrams. Only the part number is provided in the name.

PDF document of 331 KB named after the 2SC4116 part number, filed in the index under schematics.

An NPN transistor reference for the 2SC3897, supplied as a 93.9 KB PDF. Part numbers with the 2SC prefix follow the Japanese JIS scheme for NPN bipolar devices, so this…

Listed among schematics, this 155 KB PDF is named after the transistor type 2SC3788 and gives no further details such as maker or case.

PDF component sheet, 60.3 KB, covering the 2SC4920 NPN transistor from the JIS 2SC series.

For the 2SA1356, this 177 KB PDF carries just the part number, so it is most probably the device datasheet rather than a full circuit diagram.

Covering the 2SA1242, this 212 KB PDF carries only the part number in its name, so it is best treated as the component datasheet despite the schematic label.

PDF datasheet covering the 2SA1815, a part whose 2SA prefix identifies it under the JIS scheme as a PNP bipolar transistor.

The 2SA1805 PNP transistor, as indicated by its JIS 2SA prefix, is documented in this 176 KB PDF datasheet.

PDF datasheet, 44.7 KB, describing the 1T368 transistor, catalogued in the schematic section.

A 67.7 KB PDF indexed under schematics and named 1SV233, with nothing else identifying a product or board.

Named 240NQ without any suffix, this 44.6 KB PDF probably describes a family of power rectifiers sharing that prefix rather than one specific grade.

Filed under schematics, this 39 KB PDF covers the 6CWQ03F and 6CWQ04F, and the paired range in the name points to a component datasheet for two related parts, not a…

Catalogued as a schematic, this 117 KB PDF is named 400DMQ035 and states no device, brand or revision.

A 638 KB PDF named 16M-DRAM, filed as a schematic. The name indicates a 16-megabit DRAM device or document but gives no manufacturer, part number, board or revision, so…

16cyq045c is the only identifier on this 51.2 KB PDF, which the index labels a schematic.

A compact 21.9 KB PDF labelled 15mq040 and classed as a schematic. The small size and the part-number style name suggest a short datasheet for an International Rectifier…

Catalogued as a schematic, this 179 KB PDF is named after the part number 12CWQ150FN and is most likely the manufacturer datasheet for that discrete semiconductor.

PDF reference for the 6N135 and 6N136, 86 KB, catalogued under schematics. These part numbers belong to a common family of high-speed optocouplers, so the document is a…

PDF schematic for the Compal LA-A972P laptop motherboard, 1.19 MB. The file name gives only the board identifier, so brand, model and revision are not stated.

Schematic archive for the model code A145F, a small 606 KB zip whose name carries only that identifier.

PDF schematic for Compal motherboard LA-G714P. The name does not mention the laptop brand, model or revision.

Compal LA-B012P schematic in PDF, with r10 in the name most likely pointing to revision 1.0.
