Can also use 1N4001, it's a silicon diode designed for power supplies.
Voltage drop will be approx 0.7V
Anyway (regardless of part number) if it is a silicon rectification diode, the voltage drop will be approx 0.7 V. Just need to choose one that can take the intended amps.
And you can parallel them up to increase the amps if you so desire.
