Schematic diagram for the Gigabyte GA-B250M-D2V desktop motherboard, revision 1.0, in a 1.33 MB PDF.

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

PDF document for the IRFP260 power MOSFET, catalogued under schematics although the name points to a component datasheet.

A PDF reference sheet for the 2SD2259 transistor, catalogued as a schematic but in practice a component datasheet of 43.3 KB.

At 312 KB, this PDF for the 2SD2638 is the largest in its series and is probably a full datasheet with curves and outline drawings, though it is filed under schematics.

Small 27.4 KB PDF named after the part code 5LN01C, indexed as a schematic though it reads like a discrete-component datasheet.

A 27.1 KB PDF titled with the part code 5LP01SS, stored in the schematic category but evidently a small datasheet.

Small 39.9 KB PDF for the 2SD2474, carrying an _E suffix whose meaning the name does not state; it may reflect a language or edition marker.

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…

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

PDF of 43.6 KB for the 3N252, listed under schematics though the name is a bare JEDEC part number.

PDF reference of about 41.6 KB for the 3LN01C, indexed as a schematic but by name a single semiconductor 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.
