Questions

Is there a KiCad symbol and footprint for the CDBA3100-HF?

Yes. The symbol is Diode:CDBA3100-HF 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 CDBA3100-HF?

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

Where is the CDBA3100-HF datasheet?

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

Where can I order the CDBA3100-HF?

JLCPCB lists it as part C3012725, with 16 in stock; the sellers' links on this page open their listings.

What can replace the CDBA3100-HF?

Parts like it in the library: the SS310 by hongjiacheng, the SS310 by MDD, the SS510 by MDD and the SS510 by hongjiacheng. Check their datasheets: a part that fits the footprint may still differ in its ratings.

Which open-source boards use the CDBA3100-HF?

6 boards in 6 repositories on GitHub; the most starred are listed on this page, with their KiCad files.
