A 27.1 KB PDF titled with the part code 5LP01SS, stored in the schematic category but evidently a small datasheet.

PDF of 77.6 KB named 2SD1620 and filed with schematics; the name carries nothing beyond the part number, which points to a component datasheet.

PDF of 43.6 KB for the 3N252, listed under schematics though the name is a bare JEDEC part number.

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

A 166 KB PDF for the 2SD1904 transistor, listed here as a schematic but by its name almost certainly the manufacturer data sheet.

PDF documentation, 431 KB, for the 2SK2883 N-channel FET, placed in the schematic section of the catalogue.

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.

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.

Short datasheet-type PDF of 30.0 KB for the 2sk2588, an N-channel FET according to the JIS 2SK prefix.

PDF document for the 2SK2374 part, filed under schematics but named after a Japanese-registered semiconductor rather than a board.

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

Datasheet-style PDF of 142 KB for the 2SK2299N, listed as a schematic. In JIS nomenclature 2SK identifies N-channel field-effect transistors, and the trailing N is part…

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…

A compact 32 KB PDF named 2SK1447LS, filed as a schematic. It appears to cover a variant of the 2SK1447 carrying an LS suffix, whose meaning the name does not explain.

Reference sheet for the 2SK1109, with the name indicating the UTC (Unisonic Technologies) version of the part.

Datasheet document for the 2SK1103 transistor, filed as a 29.5 KB PDF. Parts beginning with 2SK are N-channel field-effect transistors registered under the JIS scheme…

Data for the 2SJ608 in a lightweight 27.9 KB PDF, indexed as a schematic. Under the Japanese JIS scheme the 2SJ prefix denotes a P-channel FET, so this is likely a…

Catalogued as a schematic, this 361 KB PDF carries only the part number 2SJ567 in its name.

Filed under schematics, the 143 KB PDF named 2SJ509 most probably holds the datasheet for a single transistor, since 2SJ in the Japanese JIS scheme designates a…

The 2SJ339 appears in this small PDF of roughly 40.7 KB. The name carries only the part number, with no hint of the equipment it came from.

A compact 47.6 KB PDF called 2SD1330_E, likely the datasheet for the 2SD1330 NPN low-frequency bipolar transistor under JIS numbering, though it is catalogued as a…

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.

Specification PDF, roughly 32 KB, for the 2SD667 transistor, listed among schematics but in fact a component datasheet.

Part-number reference for the 2SC4433 in PDF form, about 71.5 KB. The name gives no board or device, only the JIS designation, where 2SC denotes an NPN bipolar…

Indexed as a schematic, this 91.5 KB PDF named 2SC4390 is most likely the datasheet of that NPN bipolar transistor.

Filed as a schematic, this 464 KB PDF carries just the name 2SC4322 and should be read as a transistor datasheet.

Datasheet-style PDF for the 2SC4271 transistor, catalogued here under schematics and weighing 78.2 KB. The name gives only the part number, with no maker or revision.

A 107 KB PDF covering the 2SC4270, a JIS-numbered part. The 2SC prefix denotes an NPN transistor intended for high-frequency use.

Only the part number 2SC4168 identifies this 150 KB PDF, which carries a schematic label but is almost certainly a component datasheet.

This 105 KB PDF is named after the 2SC4159 and, although stored as a schematic, should contain the specification sheet for that NPN bipolar transistor, as the JIS 2SC…
