Questions

Is there a KiCad symbol and footprint for the US1B-HF?

Yes. The symbol is Device:D 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 US1B-HF?

SMA(DO-214AC), with 2 pins. Its footprint is drawn on this page.

Where is the US1B-HF datasheet?

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

Where can I order the US1B-HF?

JLCPCB lists it as part C5158719, with 2,076 in stock; the sellers' links on this page open their listings.

What can replace the US1B-HF?

Parts like it in the library: the NRVUA160V by onsemi, the UMW STTH112A by UMW, the ES1D by DongChen and the RS1M by DongChen. Check their datasheets: a part that fits the footprint may still differ in its ratings.
