Questions

Is there a KiCad symbol and footprint for the US1D?

Yes. The symbol is Diode:US1D and the footprint Diode_SMD:D_SMA, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the US1D?

SMA, with 2 pins. Its footprint is drawn on this page.

Where is the US1D datasheet?

MDD publishes it: the Datasheet link on this page opens it.

Where can I order the US1D?

JLCPCB lists it as part C472687, with 126,591 in stock; the sellers' links on this page open their listings.

What can replace the US1D?

Parts like it in the library: the US1M by MDD, the RS1M by hongjiacheng, the ES1J by GOODWORK and the ES1J by hongjiacheng. Check their datasheets: a part that fits the footprint may still differ in its ratings.

Which open-source boards use the US1D?

5 boards in 5 repositories on GitHub; the most starred are listed on this page, with their KiCad files.
