Datasheet for the 2SD2650 transistor, a 29.7 KB PDF filed in the schematic category. The file name states the part number and nothing else.

Component sheet in PDF for the 2SD2248, 100 KB, which the index places among schematics. No device or board is named, just the transistor type.

Documentation for the 2SD2241 NPN transistor, supplied as a 178 KB PDF and categorised as a schematic. The name provides only the part number.

PDF datasheet, 40.9 KB, for the 2SD2240 transistor, filed under schematics in this index. An _E suffix in the name is an edition marker for the document only.

The 2SD2225 transistor is described in this 44.3 KB PDF, listed as a schematic in the catalogue. The _E tag in the name refers to an edition of the document.
