PDF datasheet, 411 KB, for the 2SK2847, placed in the schematic category of the index. Only the part number is given in the name, with no maker or revision. In Japanese JIS/JEITA naming a 2SK code identifies an N-channel field-effect transistor. Repair technicians use such a document to confirm pinout and package, check drain-source voltage, current and on-resistance, and judge whether a cross-reference part is a safe substitute in a power stage. Verify the marking on the component before relying on the data.
