The 1N4001 diode is the most commonly used power diode used for rectification purposes and it belongs to the family of 1N400x series diodes. It is used in rectifier circuits like half-wave rectifiers, full-wave rectifiers, and diode clipper circuits to convert the applied AC voltage source to a certain DC voltage level.

One possible replacement for the 1N4001 is the 1N4004, which has the same maximum repetitive reverse voltage of 400 volts, but a slightly higher maximum average forward rectified current of 1.5 amperes. The 1N4004 is still a low-cost diode and can be a good option for rectification applications that require a higher current rating. And in one adapter, there are four diodes and a diode bridge on them, and it’s used to make an AC voltage into a DC voltage. A diode passes current only in one direction, cutting off one of the polarities.

Though some writers and datasheets refer to "1N4000 series", a 1N4000 is a 10-watt Zener diode unrelated to the 1N4001 series of 1 ampere rectifiers.The 1N4007 diode is probably the most popular of all diodes, since it is installed in the vast majority of chargers for phones, smartphones and tablets. Even if you’re holding a dollar charger and there’s no stabilization or interference filters inside, it can’t do without a diode. Since the 1N4007 is made with sufficient pin length, the diode can be mounted vertically or horizontally.
