Covering the 2SK2125 N-channel FET, this 35 KB PDF is filed under schematics, though a part-number-only name normally indicates a manufacturer datasheet.

A 34 KB PDF linked to the 2SK2123, listed as a schematic but probably the device's datasheet.

About 90 KB in size, this PDF carries only the 2SK2091 part number and is likely the datasheet for that N-channel field-effect transistor, despite being filed as a…

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.

Single-part document for the 2SK1426, supplied as a 101 KB PDF and indexed as a schematic.

PDF datasheet, 32.8 KB, for the 2SK963 N-channel FET. The 2SK prefix follows the JIS numbering convention for N-channel field-effect transistors; the name gives no…

PDF datasheet candidate for the 2SJ148, size 283 KB, indexed under schematics. JIS numbering uses 2SJ for P-channel FETs, and the name adds no maker, package or revision…

Device documentation for the 2SJ144 as a 293 KB PDF, catalogued as a schematic. A 2SJ number in the JIS system denotes a P-channel FET, so the file is most likely its…

A 339 KB PDF named for the 2SJ108, placed in the schematic category. Under JIS designations the 2SJ series are P-channel field-effect transistors, so the content is…

Reference PDF for the 2SD1220, 189 KB, listed among schematics though the number is a discrete transistor designation.

Data for the 2SC4694 transistor in a 111 KB PDF, catalogued as a schematic. The 2SC prefix identifies an NPN bipolar part under the Japanese JIS scheme, so the file is…
