Datasheet-type PDF of 419 KB named after the 2SK2314. The 2SK prefix in the Japanese JIS designation identifies an N-channel field-effect transistor, so this schematic-category file should describe that component rather than a circuit board. Look here for drain-source voltage, current rating, RDS(on), gate charge, thermal data and outline drawings. It helps when choosing an equivalent for a failed switching device. The name gives no variant information, so match the suffix and case on the original part first.
