Named only 2sd1897, this 35.6 KB PDF is listed as a schematic, yet the name is a JIS transistor number, so it is very likely a compact datasheet.

A 230 KB PDF for the 2SK2911, filed as a schematic although the bare part number suggests a manufacturer datasheet.

PDF of 137 KB for the 2SK2793, with a 1-5 suffix in the name whose meaning is not explained; it may indicate a page range or document version.

Short PDF, 43.6 KB, named after the 2SK2791 and listed as a schematic. The 2SK prefix marks an N-channel FET under the JIS scheme, so this is likely a compact datasheet.

At 214 KB, this PDF named 2SC4118 is filed as a schematic but is most plausibly a fuller datasheet for that part, likely with characteristic curves.

The 2SC4030 transistor is documented in this 119 KB PDF, which is listed in the schematic section.

Indexed as a schematic, this 55.8 KB PDF actually names a discrete part, the 2SC3930, followed by an _E suffix.

PDF document for the 2SC4853, a part number following the Japanese JIS scheme in which the 2SC prefix marks an NPN bipolar transistor.

Here the PDF, about 110 KB, is labelled with the bare part number 2SC3459 and listed as a schematic.

A 45.3 KB PDF titled with the JIS transistor number 2SC2909, filed under the schematic category.

Component reference for the 2SA1521 transistor, stored as a 30.2 KB PDF and filed under the schematic category.

Small 81.5 KB PDF named after the 2SA1724 part number and filed under schematics. Nothing else in the name identifies a product or circuit board.

The file is a 56.2 KB PDF listed under schematics and labelled 1T408, with nothing else in the name to tie it to a specific product or board.

Part number 1SS196 gives this 68.1 KB PDF its name, which marks it as a datasheet for a single semiconductor rather than a full circuit diagram.

A 42.7 KB PDF datasheet for the 1N5391 diode, listed here as a schematic although it covers a single component.

Named simply 80SQ, this 125 KB PDF is indexed as a schematic, but the code looks like a series designation for a rectifier diode family rather than a circuit diagram…

Small 34.5 KB PDF filed as a schematic and named 78P7200-IH. The name gives no laptop model or board number; it looks like an integrated circuit part number with a…

PDF of 139 KB, listed as a schematic with the code 70epf02. The name carries no laptop model, board number or revision, so the subject must be confirmed by reading the…

Catalogued as a schematic, this 49.4 KB PDF carries only the code 60LQ045 in its name, with no brand, device model or board revision.

A small PDF of 48.8 KB indexed under schematics, whose name points to a 44-lead PLCC package, most likely a package outline or socket drawing rather than a full circuit…

PDF document of 96.6 KB for the 43CTQ080L, filed as a schematic but in practice a component datasheet.

Named 35scgq045, this 70.6 KB PDF is grouped with schematics, but the name suggests a discrete component code and carries no device, brand or revision information.

The Microchip 24LC32A, a 32 Kbit I2C serial EEPROM, is documented in this 586 KB PDF that the index lists as a schematic, though it reads as a datasheet.

Datasheet in PDF for the 24AA02 and 24LC02B, 2 Kbit serial EEPROMs on the two-wire I2C bus.

PDF document of 76.9 KB named 23SC1604, listed in the schematics section. Apart from the part number the name gives no detail about the manufacturer or function, so the…

A 179 KB PDF placed in the schematic section and named only 20TQ, with no device, board number or revision mentioned.

PDF of about 158 KB named 8TQ, filed as a schematic. In International Rectifier and Vishay numbering the TQ family denotes Schottky rectifiers, and a series-level name…
