Reference document for the 2SK2793, a 141 KB PDF catalogued under schematics. The 2SK designation in the Japanese JIS system denotes an N-channel field-effect…

Datasheet-type PDF of 220 KB for the 2SC5260, carried in the schematic section of the index.

The 2SA1420 is the subject of this 91.5 KB PDF, which sits in the schematic section but by its naming is a part-level datasheet.

PDF documentation for the 2SA683 PNP transistor, sized 51.4 KB, with an _E suffix in the name that is not defined.
