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 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.

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.

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…

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

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

Reference PDF, 99.3 KB, for the 2SC3994, listed in the schematic category but named like a transistor datasheet.

Reference sheet for the 2SC5411, a PDF of 311 KB catalogued as a schematic. The name gives only the part number.

File name 2SC3786 offers nothing beyond a transistor type number, and the 81.5 KB PDF is placed in the schematic category.

Indexed as a schematic, this 95.8 KB PDF carries only the designation 2SC4821. In the JIS system the 2SC prefix denotes an NPN transistor, so the content is most likely…

For the 2SC3503, a 158 KB PDF datasheet listed with schematics. Only the part number is given; per the JIS system, a 2SC number belongs to an NPN bipolar transistor…

Named for the 2SC2995, this 510 KB PDF is listed as a schematic but most likely holds the datasheet for a JIS-numbered NPN transistor, as the 2SC prefix indicates.

Bearing only the JIS part number 2SC2879, this 167 KB PDF is listed as a schematic. A 2SC designation marks an NPN bipolar transistor, so the file most likely contains…
