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 transistor, so the file is probably the component datasheet. It supports pin identification, rating checks and selection of an equivalent part during power-circuit repair. A near-identical version carrying a 1-5 suffix is also indexed, which may be an alternate edition. Confirm the marking and package of the faulty component before choosing which sheet to trust.
