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.

Part reference for the 3N250, stored as a PDF of about 43.6 KB and catalogued in the schematic section.

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

Filed under schematics, the 39.8 KB PDF 2SD2441 with an E tag refers by its JIS-style 2SD prefix to an NPN bipolar transistor.

Small 45.6 KB PDF named 2SD1902, a Japanese standard transistor number; despite the schematic label it is most probably a short datasheet.

A compact 106 KB PDF covering the 2SK2919 transistor, indexed as a schematic though the name points to a manufacturer datasheet.

Part reference for the 2SK2862 in a 411 KB PDF, listed under schematics in this index. The name carries only the transistor number.

The 2SK2854 transistor is documented in this 125 KB PDF, indexed under schematics but almost certainly a datasheet. The name states only the part number.

Component document for the 2SK2745 in PDF form, 399 KB, filed as a schematic. Because 2SK is the Japanese JIS prefix for N-channel field-effect transistors, the file…

Datasheet-type PDF for the 2SK2740, 138 KB, with a 1-5 suffix in the name whose meaning is not stated, possibly an edition or page range.

PDF of 137 KB for the 2SK2713, carrying a 1-5 suffix of unstated meaning, likely an edition or page marker rather than a different device.

Smaller 137 KB PDF tied to the 2SK2606, a JIS-style designation where 2SK indicates an N-channel field-effect transistor.

The part number 2SK2327 is the only information in the name of this 32.8 KB PDF, filed as a schematic.

Part-number-only PDF for the 2SK2323, 23.2 KB, placed in the schematic category of the index.

Datasheet-style PDF for the 2SK1840, sized 87.3 KB. Part numbers beginning with 2SK are registered under the Japanese JIS scheme for N-channel field-effect transistors.

PDF of about 295 KB for the 2SK1827. In JIS part numbering, 2SK stands for an N-channel FET, so the content should be a datasheet rather than a board-level drawing.

Document for the 2SK1806 in PDF format, 136 KB, catalogued as a schematic. The 2SK code marks an N-channel FET under JIS naming, so the contents are likely a component…

An 88.5 KB PDF on the 2SK1738 transistor. In the JIS system, 2SK designates an N-channel FET, so this file is most likely the datasheet rather than a circuit schematic.

The 2SK1456 is the only information in the name of this 124 KB PDF, which is indexed as a schematic.

Datasheet for the 2SD882 NPN transistor in a 165 KB PDF; the file name does not state which manufacturer issued it, unlike the UTC versions in the same set.
