Datasheet PDF, 537 KB, named only with a generic numbered copy label, so neither the component nor its maker is identified. Open it to find out what part it describes before using it in a repair. A component datasheet normally gives pin functions, electrical limits, typical application diagrams and package outlines, which are needed to measure correct pin voltages, confirm a part has failed and choose a compatible replacement. Renaming the file to its real part number after checking will make it much easier to find later.
