PDF datasheet, 171 KB, whose name is only a numeric code, 1302440201, so neither the component nor its maker can be determined from the title. Open the file to read the part number and manufacturer on its first page. Component datasheets are used during board repair to confirm pinouts, package dimensions, electrical limits and typical application circuits, which helps when checking whether a chip is faulty or when looking for a compatible replacement. Make sure the marking on the actual part matches the document before trusting the pin assignments.
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 @ic_mosfet_pdf_datasheets. Enginerys does not host this file.
