Not if you want to attach it to a Space Force robot to shoot down satellites!

And now for something completely different!
A serious answer.
You need to know the forward voltage of the diode and the maximum current it will take. Get that from the datasheet.
Remember Kirkhoff's Law, all voltages must add up.
So V in the following equation will be Source Voltage minus Forward Voltage.
R = V/I
where R is resistance in Ohms and I is the maximum current in Amps.
This should answer your question!
