Specification document, 405 KB in PDF form, for the 2SK2604 transistor. Japanese JIS part numbering assigns the 2SK prefix to N-channel field-effect transistors; beyond that, the name reveals no package, maker or application. Despite the schematic label it is best read as a datasheet. Technicians consult it for pinout and ratings when a power supply or motor driver stage has a blown MOSFET and a substitute must be sized correctly. Cross-check the marking and case style on the original part.
