A 106 KB PDF named 88cnq060, indexed as a schematic, though by its number it is most likely an earlier datasheet for a dual Schottky rectifier module rated around 60 V reverse voltage. The name does not give the vendor or date, and a larger 88cnq060a edition exists in the index. Use it to confirm pin arrangement, forward drop and current rating when diagnosing a failed rectifier in a power supply. Test the part out of circuit and match package and ratings when choosing a replacement.
