Copy of documentation for the 2SK2294, 135 KB in PDF, with an _1-5 suffix in its name that is not explained and may indicate a different edition or page selection. The 2SK prefix is the JIS designation for an N-channel FET, so treat this schematic-labelled file as a datasheet. Use it to verify pinout, absolute maximum ratings and electrical characteristics when diagnosing or replacing the transistor. A separate 2SK2294 file is also catalogued; compare both and check the part marking first.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @cyberlanelectonik. Enginerys does not host this file.
