Questions

Is there a KiCad symbol and footprint for the US2B-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 US2B-HF?

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

Where is the US2B-HF datasheet?

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

Where can I order the US2B-HF?

JLCPCB lists it as part C17591471, with 0 in stock; the sellers' links on this page open their listings.

What can replace the US2B-HF?

Parts like it in the library: the ES2DHE3-LTP by Micro Commercial Components, the RF201L2SDDTE25 by ROHM Semiconductor, the VS-3EYH02HM3/H by Vishay Intertechnology and the RS2MAL by Taiwan Semiconductor. Check their datasheets: a part that fits the footprint may still differ in its ratings.
