Small 38 KB PDF named for the 10BF10 to 10BF80 range and indexed as a schematic. The name indicates a diode family covering several voltage grades in a single sheet, so treat it as a component datasheet. Open it in any PDF viewer to compare ratings across the range, read the package outline and check pin polarity. It is handy when a rectifier has failed and the exact grade must be matched or exceeded. Read the full number from the original part to choose the right row in the table.
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.
