PDF of 363 KB for the 2SK192A, listed among schematics but named after a single JIS part, with an A suffix that the name explicitly includes.

The 2SK3121 is covered by this 126 KB PDF, which the index lists as a schematic although it serves as a part datasheet.

A 368 KB PDF covering the 2SK2998, a part whose 2SK prefix follows the Japanese JIS scheme for N-channel FETs.

The 2SK2995 is the subject of this 418 KB PDF, filed among schematics but by its name a transistor datasheet.

A compact 136 KB PDF for the 2SK2989, listed as a schematic yet by name a discrete transistor document. Under the JIS convention 2SK marks an N-channel FET.

Very small 26.9 KB PDF for the 2SK2951, likely a short datasheet or summary page given its size.

Part sheet for the 2SK2698, delivered as a 413 KB PDF. Following JIS naming, 2SK parts are N-channel FETs, and the file size points to a complete datasheet with graphs…

A 30.3 KB PDF on the 2SK2659, listed in the schematic section but in practice the documentation of a single N-channel FET, as indicated by the JIS 2SK prefix.
