Indexed under schematics, this 71.1 KB PDF carries the part code 80SCLQ045, part of the same family as the 030 and 060 sheets in this collection and resembling International Rectifier Schottky rectifier naming. It should be read as a single-part datasheet. Technicians consult such a document for pinout, outline drawing and forward and reverse characteristics before measuring or replacing a diode. Confirm that the digits printed on the component match this sheet rather than a neighbouring grade.
