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

PDF reference for the 2SK2993 transistor, 424 KB. The file name carries only the part number, which under the JIS scheme denotes an N-channel field-effect transistor, so…

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.

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.

Short 27.9 KB PDF covering the 2SK2625LS transistor. Its base number follows the JIS 2SK convention for N-channel FETs, and the LS ending marks a variant such as an…

Named 2SK2398, this 410 KB PDF appears in the schematic category yet reads as a transistor datasheet by its number; JIS codes beginning 2SK cover N-channel field-effect…

Named only 2SK1463, this 121 KB PDF is grouped with schematics but concerns a discrete part: the Japanese 2SK prefix means an N-channel FET.

PDF reference of 102 KB for the 2SK1428 field-effect transistor, filed among schematics.

Here the 2SK1422 transistor is documented in a 103 KB PDF filed under schematics, though content is most likely a datasheet rather than a board diagram.

Datasheet in PDF format for the 2SK932, around 91.5 KB. The 2SK prefix denotes an N-channel FET registered under JIS numbering, and the file name contains no extra…

Technical PDF for the 2SJ313, 238 KB in size. The file name identifies only this component, with no device or revision details.

For the 2SD893, this 53.8 KB PDF includes an _E suffix in its name whose meaning is not given.

Part documentation for the 2SC4727 in a 108 KB PDF. Catalogued under schematics, the file is named for a component whose 2SC prefix marks an NPN bipolar transistor in…

Component reference for the 2SC5197 in a 171 KB PDF, matching the size of related 2SC519x files and possibly sharing one manufacturer sheet with them.

Listed under schematics, this 133 KB PDF named 2SC5108FT appears to be the datasheet for an FT-suffixed variant of the 2SC5108 transistor.

PDF reference for the 2SC4248 transistor, 300 KB in size. Beyond the part number the file name gives no information about manufacturer, package or revision.

A brief 37.5 KB PDF identified only by the part number 2SC5710. JIS numbering assigns 2SC to NPN bipolar transistors, so this is likely a concise datasheet.

Datasheet-style PDF, 217 KB, for the 2SC3668 transistor; the name supplies no other details.

The 2SC3666 is documented here in a 175 KB PDF. Following JIS semiconductor naming, 2SC designates an NPN bipolar transistor, and since the name holds only the part…
