Compact 53 KB PDF named for the 10DF1 to 10DF8 range, indexed as a schematic. The name appears to describe a family of diodes spanning several voltage grades in one datasheet rather than a circuit drawing. Open it in any PDF reader to read maximum reverse voltage, average forward current, surge rating and package outline. Such sheets help pick an equivalent part when the original rectifier on a board is damaged. Match the exact grade number on the component body to the table before substituting.
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.
