Datasheet for the 1N5402, a 200 V member of the 3 A 1N5400 rectifier family, kept as a 43.4 KB PDF and listed under schematics. The name states only the part number. The sheet should contain maximum ratings, characteristic graphs and package dimensions. Technicians use it to verify ratings of a rectifier in a low-voltage supply or charger and to choose a replacement of equal or higher voltage grade. Read it in a standard PDF viewer and confirm polarity on the board silkscreen.
