Source for diodes

I have a switch where a diode was shorted on the display driver. I removed a diode from another switch i was waiting for parts for, and its display driver, and the original switch now works.

However the switch i removed the parts from now needs a replacement diode. I dont have any donor boards.

I see from the data sheet for the display driver that its a schottky type, and the size looks to be 0402 but hve not been able to find a part number, or find any that may be a suitable replacement, that are avilable in low numbers in the uk. Any ideas?
