A 322 KB PDF datasheet for the 2SK2613, indexed under schematics. The 2SK prefix is the Japanese JIS registration for N-channel FETs, and the file size points to a complete sheet with tables, curves and a package drawing. Use it to locate gate, drain and source, to check whether diode-test results suggest a failed device and to compare equivalents for replacement. Make sure the printed part number and package on the board match before relying on the specifications.
