Stored under schematics, this 171 KB PDF is named 2SD1407A and is most probably the datasheet for that transistor variant, the A suffix distinguishing it from the base…

Datasheet PDF for the 2SA1681 transistor, 185 KB, listed in the schematic category. Only the part number is stated in the name.

Dell schematic for the desktop board shared by the XPS 8500 and Vostro 470, identified by the Cypress Point code name (misspelled in the name).

PDF datasheet covering the 2SD2251 NPN transistor, 95.7 KB in size and listed under the schematic category. The name contains nothing beyond the part number.

PDF of about 179 KB for the 2SD2531, filed as a schematic but probably the component datasheet.

PDF reference, about 137 KB, for the 2SC4614 transistor. Although categorised as a schematic, a bare part-number name like this normally indicates a datasheet rather…

Datasheet candidate for the 2SC4455 transistor, a 100 KB PDF although filed with schematics.

The smaller 77.9 KB PDF here carries the type number 2SC4449, indexed as a schematic but almost certainly a component datasheet.
