Questions

Is there a KiCad symbol and footprint for the SMAJ85A?

Yes. The symbol is Diode:SMAJ85A 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 SMAJ85A?

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

Where can I order the SMAJ85A?

JLCPCB lists it as part C55222984, with 5,000 in stock; the sellers' links on this page open their listings.

What can replace the SMAJ85A?

Parts like it in the library: the SMAJ85A by hongjiacheng, the SMAJ85CA by TDD, the SMAJ85A by TECH PUBLIC and the SMAJ85CA by TECH PUBLIC. Check their datasheets: a part that fits the footprint may still differ in its ratings.
