Reference material for the 3SK272 in a 30.2 KB PDF, filed under schematics. The name carries no detail other than the type number. Per the Japanese JIS scheme, 3SK indicates an N-channel FET with four terminals, most often a dual-gate MOSFET in VHF or UHF tuner circuits. A repairer would read it for lead identification, gain and noise data and absolute limits when choosing a replacement, and should verify the package outline matches the pads on the board before soldering.
