Datasheet-style PDF for the 10CTQ150, about 135 KB, listed in the index as a schematic. In International Rectifier and Vishay naming the CTQ family is a center-tap dual Schottky rectifier, so the document should give pinout for both diodes, reverse voltage, forward drop and package drawing. It is useful for checking a shorted secondary rectifier in a power adapter or PSU and finding a correct replacement. Measure each half of the device separately and verify the marking before ordering.
