A 214 KB PDF for the 2SA1429 part, catalogued as a schematic though most likely a data sheet.

PDF reference of 43.6 KB covering the 2SA1258. No device, board or revision is mentioned, only the component code, whose 2SA prefix denotes a PNP transistor in the…

Datasheet PDF for the 2N4031 part number, 52.3 KB in size, placed in the schematic category of the index.

At 33.6 KB, this PDF named 1N746 is a short component datasheet for the original non-suffixed part of the 1N746 zener family, indexed under schematics.

Rectifier datasheet for the 1N5407, the 800 V member of the 3 A 1N5400 family, held as a 43.4 KB PDF in the schematic section.

Specification sheet for the 1N5283, saved as a 119 KB PDF and indexed as a schematic. Its size matches the 1N5292 file, which hints that both are the same series…

PDF document of 246 KB tied to the 1N4001 rectifier, catalogued under schematics. The plus sign in the name is uninformative and does not identify a vendor or revision…

Indexed under schematics, this 181 KB PDF named 28512 most likely documents a 28-series 512 Kbit parallel EEPROM, though the name does not confirm the manufacturer or…

Grouped with schematics, this 153 KB PDF is named 85epf080 and gives no brand, device or revision.

Schematic for a model named SL410K, supplied as a 1.58 MB PDF; the name states no brand, board number or revision, so read the title block to confirm the platform.

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.

PDF boardview for the Gigabyte GA-F2A55M-DS2, revision 1.01. The drawing shows component placement and reference designators for this AMD A55 chipset FM2 motherboard and…
