Questions

Is there a KiCad symbol and footprint for the SA20A?

Yes. The symbol is Device:D_TVS and the footprint EasyEDA_Cloud:DO-15_BD3.1-L6.7-P10.70-D0.8-RD, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the SA20A?

DO-15(DO-204AC), with 2 pins. Its footprint is drawn on this page.

Where is the SA20A datasheet?

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

Where can I order the SA20A?

JLCPCB lists it as part C1974883, with 3,740 in stock; the sellers' links on this page open their listings.

What can replace the SA20A?

Parts like it in the library: the SMBJ20A by MDD, the SMF20CA by hongjiacheng, the SMBJ20A by BORN and the SMAJ20CA by hongjiacheng. Check their datasheets: a part that fits the footprint may still differ in its ratings.
