This PDF of about 124 KB covers the 2SD2114 transistor with a KS suffix; the suffix is not explained by the name and may denote a gain class or package variant.

Datasheet PDF, 60 KB, for the 2SD1650, with the name given in lowercase and filed under schematics.

Compact 43.6 KB PDF named for the 3N249 and filed as a schematic, although it is almost certainly a component datasheet.

Part number 2SD2459 names this 41.2 KB PDF, followed by an unexplained E tag; it is catalogued as a schematic.

Largest in this set at 269 KB, the PDF 2SD2414 is catalogued as a schematic, yet its 2SD prefix marks an NPN bipolar transistor under the Japanese JIS scheme.

The 2SK3413LS is documented in this compact 32.2 KB PDF, indexed as a schematic but effectively a component datasheet.

Datasheet-type PDF of 31.1 KB for the 2SK3412 semiconductor, stored under the schematic category.

For the 2SK3411 transistor, this 32.0 KB PDF provides the component reference, even though the index files it as a schematic.

The 2SK3291 transistor is the subject of this 34.2 KB PDF, filed as a schematic although it works as a datasheet.

Here the 2SK3285 is documented in a 48.6 KB PDF, placed in the index's schematic section.

Datasheet-style PDF for the 2SK3018, indexed here under schematics, though the 2SK prefix marks a Japanese JIS-registered N-channel field-effect transistor rather than a…

PDF reference for the 2SK2825, 301 KB in size and listed in the schematic section. The 2SK designation, from the Japanese JIS numbering system, belongs to N-channel…
