2. Characteristics and working principle of 1N4001

The 1N4001 is a diode that has two main characteristics: forward conduction and reverse blocking. In forward conduction, when a forward voltage is applied to the diode, it allows current to pass through, which is necessary to convert AC to DC. When a reverse voltage is applied to the diode, it blocks the flow of current, acting as a protection circuit.

The 1N4001 has a reverse voltage tolerance of 50V, which means it can prevent voltages above 50V from passing through. This makes it ideal for the rectification of low-voltage DC power supplies.
