Questions

Is there a KiCad symbol and footprint for the SS54-HF?

Yes. The symbol is Device:D_Schottky 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 SS54-HF?

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

Where is the SS54-HF datasheet?

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

Where can I order the SS54-HF?

JLCPCB lists it as part C3757794, with 0 in stock; the sellers' links on this page open their listings.

What can replace the SS54-HF?

Parts like it in the library: the SS54 by MDD, the SS54 by hongjiacheng, the SS56 by hongjiacheng and the SS510 by MDD. Check their datasheets: a part that fits the footprint may still differ in its ratings.

Which open-source boards use the SS54-HF?

4 boards in 3 repositories on GitHub; the most starred are listed on this page, with their KiCad files.
