Concise 37.7 KB PDF for the 2SK2464, filed among schematics yet named after a single semiconductor. Japanese JIS part numbering uses 2SK for N-channel field-effect transistors, and nothing further about the device appears in the name. A short sheet like this typically gives pinout, maximum ratings and package outline. Consult it before testing a suspected shorted FET or ordering a replacement, and confirm the marking on the original part matches this number exactly.
