Compact 68.2 KB PDF datasheet named only by the number 72029, which reads like a manufacturer document number rather than a part name. Vishay, for instance, labels many of its MOSFET datasheets with five-digit document numbers, but the actual device must be confirmed by opening the file. Small sheets like this usually hold a pinout, ratings table and package drawing. Technicians use them to check pin identity before probing for shorts and to choose a replacement with matching voltage, current and package.
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.
