Labelled only 241NQ, this 45.4 KB-class PDF of 45.2 KB appears to be a series datasheet for a family of power rectifier devices, with no suffix pinning it to a single grade. It is catalogued as a schematic though it is not a circuit drawing. Use it to compare members of the series, confirm terminal layout and read thermal and electrical limits before replacing a module. Open it with any PDF viewer, and pick the correct entry by matching the full code on the device itself.
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.
