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.

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 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…

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.

The 2SK2035 transistor is the subject of this 295 KB PDF, most likely the manufacturer datasheet given that 2SK is the JIS prefix for N-channel FETs.

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.

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.

The 2SK1839 is covered in this 84.9 KB PDF, filed under schematics though the name points to a single semiconductor part.

A 291 KB PDF dedicated to the 2SK1830. The 2SK code is the Japanese JIS designation for N-channel field-effect transistors, so this is almost certainly a datasheet…

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 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 2SK664 transistor, this 34.9 KB PDF is indexed as a schematic but, judging by the JIS 2SK naming used for N-channel field-effect transistors, it is a datasheet…

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…

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…

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.

Nothing beyond the code 2SJ272 is given in the name of this 92.3 KB PDF. Japanese JIS numbering assigns the 2SJ prefix to P-channel field-effect transistors, so the…

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.

A 177 KB PDF describing the 2SC4689, placed in the schematic category of the catalogue.

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…

PDF for the 2SC4417 carrying an _E suffix whose meaning the name does not explain, sized 40.7 KB.

Datasheet-style PDF of 44.0 KB for the 2SC4391, filed as a schematic; the trailing _E suffix in the name is not explained and could denote an edition or language…

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 PDF for the 2SC5575, 52.0 KB, placed in the schematic section of the index. The file name contains only the part number.

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…

Indexed as a schematic, this 296 KB PDF is named only 2SC5094, a JIS-style transistor designation where 2SC stands for an NPN device rated for high-frequency operation.
