Document for the 3SK227 semiconductor, stored as a 30.6 KB PDF and catalogued under schematics. The 3SK numbering comes from the Japanese JIS scheme for four-terminal FETs, a family widely found in VHF and UHF amplifier and mixer stages. Expect pin assignment, electrical characteristics and package drawing rather than a full circuit. When hunting for a replacement, match the gate arrangement and SMD marking against the failed device, since similar numbers in this range often differ in package and gain.
