This 194 KB PDF is labelled simply 113cnq and filed as a schematic, with no device, board number or revision in the name. The code matches the style of dual Schottky rectifier series names and lacks a voltage suffix, so it likely covers several grades of one part family. It opens in any PDF viewer. Use the ratings table and package drawing when diagnosing or replacing a power diode, and take the exact voltage grade from the marking printed on the component itself.
