Named after the 151cnq035, this 53.2 KB PDF is filed under schematics but fits the pattern of a dual Schottky rectifier datasheet, with 035 normally meaning a 35 V reverse rating. Inside should be maximum ratings, thermal resistance, characteristic curves and outline drawing. It is used to verify a replacement for shorted output rectifiers in high-current power supplies. Open in a standard PDF reader, and confirm the package type and full marking on the original part before installing a substitute.
