This 80.9 KB PDF for the 160cnq035 is filed as a schematic, but the code matches a high-current dual Schottky rectifier, the 035 ending usually indicating 35 V. It should contain absolute maximum ratings, thermal resistance, forward and reverse curves and package outline. Useful for confirming a correct replacement in server, telecom or welding power supplies where these rectifiers handle large output currents. Check the full part marking and package, as CNQ and CMQ variants are not physically identical.
