Filed under schematics, 35clq045 is a 47.8 KB PDF whose name reads like a discrete part number; it does not state any device, manufacturer or revision. Technicians use reference sheets of this type to identify pins, confirm mounting style and read maximum ratings, which is useful when a component in a supply circuit has failed and a replacement must be chosen. Open it in any PDF reader. Compare the complete marking on your part, because letter and digit variations in the code indicate a different member of the series.
