Datasheet-type file for the 2SK1464 N-channel field-effect transistor, 120 KB in PDF form and indexed as a schematic. The name carries nothing beyond the part number, which follows the Japanese JIS 2SK pattern. Technicians typically use this kind of sheet to identify terminals, look up breakdown voltage, continuous drain current and power dissipation, and assess replacements when the original is obsolete. Check the marking on the component closely, as nearby codes in this series differ by only one digit.
