Named 244NQ035, this 44.5 KB PDF is indexed under schematics but its title is a component part number from a family of power rectifiers, so treat it as a datasheet. The manufacturer is not stated in the file name. It is useful for confirming ratings, package outline and pin or terminal polarity when diagnosing a shorted or open module. View it in any PDF reader, and make sure the suffix digits on the actual part match, because sibling numbers in the series differ in their rated values.
