Series datasheet in PDF form, 169 KB, for the 203CNQ family of Schottky rectifier modules. The name carries no voltage suffix, so the document probably covers several voltage grades in one sheet. Although it is catalogued as a schematic, expect ratings tables, forward characteristic curves and mechanical dimensions rather than a circuit board. Use it to pick the correct grade when replacing a failed rectifier, and read the full part code on the original component to match the exact voltage rating.
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.
