Part number 80SCLQ030 is all the name of this 48.1 KB PDF reveals; it sits in the schematic category but the code points to a Schottky rectifier datasheet in International Rectifier style. No laptop, board or brand is involved. The sheet is useful for checking package type, which terminals are anode and cathode, and the limits a substitute must satisfy. Sibling sheets for 045 and 060 grades exist, so compare the full marking on the component before trusting the figures here.
