A 413 KB PDF for the 2SK2699 transistor, filed as a schematic in this index. The 2SK prefix identifies it as a JIS-registered N-channel field-effect transistor, so the document is almost certainly a manufacturer datasheet. Expect pin assignments, a package drawing, ratings and switching characteristics. Use it when diagnosing a shorted MOSFET in a power circuit and when cross-referencing substitutes. Read the gate threshold and voltage limits carefully before choosing an alternative part.
