Component document for the 2SK2745 in PDF form, 399 KB, filed as a schematic. Because 2SK is the Japanese JIS prefix for N-channel field-effect transistors, the file should be the part datasheet rather than a circuit diagram. It is useful for locating gate, drain and source on the package, for comparing on-resistance and voltage ratings against candidate replacements, and for understanding why a part may fail short in a power stage. The name offers no revision or manufacturer information, only the part number.
