A 75.3 KB PDF called 15clq100, filed in the schematic category. The name looks like a discrete Schottky rectifier part number of the kind used by International Rectifier and Vishay, so a datasheet with ratings, characteristic curves and package dimensions is the likely content. Use it to check pinout and polarity before desoldering, and to confirm voltage and current ratings when sourcing a substitute. Verify that the code on the physical component matches the file before applying any value.
