PDF documentation, 431 KB, for the 2SK2883 N-channel FET, placed in the schematic section of the catalogue. The file name gives only the part number, so manufacturer and revision are not indicated. The 2SK prefix belongs to the Japanese JIS/JEITA registration scheme. A technician uses such a sheet when a transistor tests shorted, to confirm which pin is the gate, check voltage and current limits and choose a compatible substitute in the same package. Verify the marking on the device before trusting the data.
