Repair guide in PDF form for the ASUS UX305FA ultrabook, catalogued under schematics at 1.2 MB.

Datasheet-style PDF, 142 KB, for the 74HC595D, the familiar 8-bit serial-in, parallel-out shift register with output latches; the D suffix usually marks the SO package.

Small 67.8 KB PDF for the 2SD1854, a part number in the Japanese 2SD series of NPN bipolar transistors, so it is really a datasheet rather than a full schematic.

A 29.2 KB PDF documenting the 2SD2639 part, catalogued as a schematic. Nothing beyond the type number is stated in the name.

For the 2SD2098 transistor, this 159 KB PDF is categorised as a schematic but follows the usual naming of a part datasheet.

Datasheet PDF, 43.0 KB, for the 2SD2321, with an _E suffix carried over from the original name, though the suffix itself is not explained.

Here the 2SK2746 is documented in a 420 KB PDF, categorised as a schematic yet named like a single-part datasheet.

Covering the 2sk2580, this 34.5 KB PDF is labelled a schematic yet identifies only a semiconductor part, pointing to a short datasheet.

The 2SK2545 is the subject of this 415 KB PDF, catalogued as a schematic but by its name a discrete transistor document.

PDF reference for the 2SK2339 transistor, 35.9 KB, catalogued under the schematic type.

A 32.6 KB PDF covering the 2SK2325, a Japanese-registered semiconductor whose 2SK prefix means N-channel field-effect transistor.

Datasheet in a 33.2 KB PDF for the 2SK1967, a Japanese-registered N-channel field-effect transistor indicated by the 2SK prefix.

Datasheet PDF, 292 KB, for the 2SK1829 transistor. Under JIS naming, 2SK marks an N-channel FET; the file name gives only the part number, with no maker or package…

PDF, 121 KB, for the 2SK1474 transistor. Japanese 2SK numbering denotes an N-channel field-effect device, so although the index category is schematic, the content is…

Catalogued among schematics, the 43.5 KB PDF called 2SJ499's neighbour 2SJ485 refers to a semiconductor part; under the JIS scheme the 2SJ prefix designates a P-channel…

Small 43.1 KB PDF for the 2SJ400, likely a short datasheet despite being indexed as a schematic.

A 92.5 KB PDF named after 2SJ256, a JIS-numbered P-channel field-effect transistor according to its 2SJ prefix.

The 2SD1198 is the subject of this 56.6 KB PDF, filed as a schematic although the name points to a component datasheet; an _E suffix follows the part number with no…

A 161 KB PDF carrying only the part number 2SC4650, a JIS-registered NPN transistor. Nothing in the name links it to a specific device, so treat it as a component…

PDF document, 39.0 KB, for a part named 2SC4627J, with an extra _E tag in the name whose meaning is not stated.

Catalogued as a schematic, this 184 KB PDF is named only after the part number 2SC5175, so it is most likely the manufacturer datasheet for that discrete transistor.

Named only after the part 2SC4363, this 88 KB PDF is catalogued as a schematic but is most likely the manufacturer datasheet for that transistor.

Despite sitting in the schematic category, this 99.9 KB PDF is named after the 2SC4164 and should therefore contain transistor specifications rather than a circuit…
