Brief 114 KB PDF for the 2SK2965, labelled a schematic but by its name a datasheet for a single N-channel field-effect transistor, as the JIS 2SK prefix indicates.

Transistor datasheet PDF, 422 KB, for the 2SK2949. Under the JIS convention a 2SK number identifies an N-channel field-effect transistor, so this describes one device…

Datasheet-style PDF for the 2SK2126, around 34 KB, indexed as a schematic. The JIS prefix 2SK marks it as an N-channel field-effect transistor, and the name says nothing…

Named only for the 2SK2074, this 95 KB PDF is catalogued as a schematic but is most likely the transistor's datasheet.

PDF datasheet, 113 KB, for the 2SK1690, which the Japanese 2SK numbering identifies as an N-channel FET.

NEC datasheet in PDF form for the 2SK1584, 57.9 KB, with the manufacturer given directly in the file name.
