Component datasheet in PDF form, 141 KB, catalogued under the literature code SDZS010. The name identifies only the document number, not the chip, so read the cover page to learn which part and package it describes. For repair work a datasheet like this is the reference for pin functions, supply voltage limits and expected signal levels, letting you compare measurements taken around the IC with what the manufacturer specifies and decide whether the part has failed.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @datasheet_technar_org. Enginerys does not host this file.
