Short 39.5 KB PDF grouping the 6CWQ09F and 6CWQ10F, dual Schottky rectifiers in the 6CWQ range, with the numbers most likely marking 90 V and 100 V grades. The file is a component datasheet rather than a board schematic, and no end device is named. It provides ratings, characteristic curves and a package outline useful when sourcing a replacement for a failed rectifier in a power supply output. Compare the full marking on the original component to pick the correct grade.
