Overview
The UST1K is a switching Diode made by DIOTEC in a DO-214AC(SMA) package with 2 pins.
PCBKit's library has its KiCad symbol (Device:D, from KiCad's library) and its footprint (Diode_SMD:D_SMA, from KiCad's library), ready for a KiCad board. JLCPCB lists it (part C17316800).

Is there a KiCad symbol and footprint for the UST1K?
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 UST1K?
DO-214AC(SMA), with 2 pins. Its footprint is drawn on this page.
Where is the UST1K datasheet?
DIOTEC publishes it: the Datasheet link on this page opens it.
Where can I order the UST1K?
JLCPCB lists it as part C17316800, with 0 in stock; the sellers' links on this page open their listings.
What can replace the UST1K?
Parts like it in the library: the RS1M by Slkor, the US1K-E3 by Vishay Intertechnology, the VS-E7MH0112-M3 by Vishay Intertechnology and the US1M-M3 by Vishay Intertechnology. Check their datasheets: a part that fits the footprint may still differ in its ratings.
