Revision 2 of a datasheet for the 1N5400, the 50 V base grade of the 3 A rectifier series, supplied as a 44.9 KB PDF and indexed under schematics. The dx tag probably refers to the issuing vendor document code, but the name does not confirm the company. It typically covers the whole family ratings, curves and axial package dimensions. Technicians use it to identify voltage grades across the series and choose a replacement. Match current rating, lead spacing and cathode orientation before fitting.
