Software package named LCIIT 2UUL PC Interface Tool, delivered as a 30.7 MB zip archive.

PDF of about 105 KB named after the 2SK2043 transistor, catalogued as a schematic although it is likely the part datasheet.

Component datasheet for the 2SD1851 transistor, supplied as a 93.4 KB PDF and classed as a schematic in the index.

Documentation for the 2SD2599, a 251 KB PDF catalogued among schematics, larger than many single-part sheets and possibly containing characteristic curves and package…

A 40.8 KB PDF giving data on the 2SD2629, stored in the schematic category. Only the part number is present in the name.

The 2SD1804 transistor is the subject of this 158 KB PDF, indexed under schematics though its name indicates a datasheet.

Documentation for the 2SD1802 in a 150 KB PDF, filed as a schematic though the name suggests a transistor datasheet.

Part 2SD2551 is the subject of this PDF of about 232 KB, filed under schematics but most likely a component datasheet.

PDF of about 30.7 KB for the 5LP01S, categorised as a schematic though it most likely contains the component datasheet.

A 41.4 KB PDF datasheet for the 5LP01M, listed in the schematic section of the index. Beyond the part code the name tells nothing more; LP in this series seems to…

Listed under schematics, the 2SD2100 PDF of 144 KB is in practice a reference sheet for a single discrete part.

The 2SD2099 part number is the only detail in this 126 KB PDF name, which points to a datasheet for a Japanese-coded transistor.

Only the part number 2SD2088 appears in the name of this 171 KB PDF, so treat it as the datasheet for that transistor.

Datasheet-style PDF of 179 KB named for the 2SD2525, catalogued as a schematic but describing just one component.

A 167 KB PDF identified only by the 2SD2481 part number, which points to the datasheet for that transistor rather than a board schematic.

The 3SK286 is documented in a 22.3 KB PDF listed under schematics, a size and name typical of a short component datasheet.

Reference material for the 3SK272 in a 30.2 KB PDF, filed under schematics. The name carries no detail other than the type number.

A 69.5 KB PDF for the 3SK248, catalogued as a schematic and most likely a manufacturer datasheet for the part. Only the type number is stated.

Datasheet-style PDF named for the 3N257, roughly 42 KB and listed in the schematic category.

At 180 KB, this PDF named 2SD2449 is larger than most of its neighbours and is catalogued as a schematic.

Indexed as a schematic, the 305 KB PDF named 2SK208 most likely holds the datasheet for that Japanese JIS-numbered part.

Named after the JIS designation 2SK184, this 307 KB PDF is tagged as a schematic but is most likely the device datasheet.

A 333 KB PDF for the 2SK170, filed under schematics though its name is a plain JIS part number, suggesting a datasheet.

Tagged as a schematic, this 28.3 KB PDF bears the JIS designation 2SK3449 and is best regarded as the datasheet for that component.

A 32.0 KB PDF covering the 2SK3415LS transistor, catalogued as a schematic though it reads as a part datasheet. Under JEITA naming, 2SK marks an N-channel FET.
