The 2SK2094 N-channel FET is the subject of this 127 KB PDF, which is catalogued as a schematic though the bare part-number name points to a datasheet. The 2SK prefix comes from the Japanese JIS registration system. No brand or package is stated. Its use in repair is checking ratings and pinout when testing a suspected shorted transistor or selecting a compatible substitute. A copy with a 1-5 suffix is also listed for comparison.
