A 137 KB PDF for the 2SK2714 with a 1-5 suffix that the name leaves unexplained, possibly an edition or page range. The plain-named file for the same part is also in the index. Since 2SK is the JIS designation for N-channel FETs, the document functions as a component datasheet despite the schematic label. Consult it for pinout, drain-source voltage, current rating and threshold voltage when testing a suspect transistor or picking a substitute for a failed one.
