PDF for the 2SC1172, 74.4 KB, listed among schematics with no further detail in its name.

PDF document for the IRFP260 power MOSFET, catalogued under schematics although the name points to a component datasheet.

A PDF reference sheet for the 2SD2259 transistor, catalogued as a schematic but in practice a component datasheet of 43.3 KB.

Small 27.4 KB PDF named after the part code 5LN01C, indexed as a schematic though it reads like a discrete-component datasheet.

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 covering the 3SK189, about 178 KB in size and listed in the schematic category, though the name points to a single component datasheet.

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.

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

A 365 KB PDF for the 2SK2859, filed under the schematic type though it is most probably a manufacturer datasheet. Nothing other than the part number appears in the name.

A compact 134 KB PDF titled with the part number 2SK2839 and catalogued as a schematic.

Datasheet-style PDF of 21.4 KB for the 2SK2751, listed under the schematic category. The 2SK designation belongs to the Japanese JIS system and marks an N-channel…

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…

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.

A 416 KB PDF covering the 2SK2610, a JIS-designated part whose 2SK prefix identifies an N-channel FET.

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

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

Copy of documentation for the 2SK2294, 135 KB in PDF, with an _1-5 suffix in its name that is not explained and may indicate a different edition or page selection.

Small 30.0 KB PDF covering the 2SK2047 transistor. Under the JIS naming system the 2SK prefix marks an N-channel FET, so this is best treated as a part datasheet rather…

PDF of 33.4 KB describing the 2SK2016 transistor, an N-channel FET by its JIS 2SK prefix. It is catalogued as a schematic but is best used as a component datasheet.

A 34.3 KB PDF for the 2SK1846 transistor. The 2SK prefix follows the Japanese JIS convention for N-channel FETs, so this is probably a part datasheet even though it is…

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.

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…

The 2SK1489 named here is a discrete transistor code: under JIS numbering, 2SK denotes an N-channel field-effect transistor.

Reference PDF for the 2SK1457, filed under schematics and 122 KB in size. The file name carries only the part number.

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

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.

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…

For the 2SK614, a part number from the JIS family of N-channel field-effect transistors, this 32.7 KB PDF is catalogued as a schematic but is most plausibly a short…

A 29.4 KB PDF for the 2SJ569LS, catalogued as a schematic though it is named in the style of a component datasheet.

Compact 42 KB PDF for the 2SJ340, catalogued among schematics although the name is a transistor part number. Nothing else about a device or board is stated.
