Questions

Is there a KiCad symbol and footprint for the SMA6F20A?

Yes. The symbol is Device:D_TVS and the footprint EasyEDA_Cloud:SMA_L4.3-W2.6-LS5.2-RD, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the SMA6F20A?

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

Where is the SMA6F20A datasheet?

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

Where can I order the SMA6F20A?

JLCPCB lists it as part C1975964, with 0 in stock; the sellers' links on this page open their listings.

What can replace the SMA6F20A?

Parts like it in the library: the P6SMAJ20ADF by Diodes Incorporated, the SMA6L20A by Littelfuse, the TPSMA6L20A by Littelfuse and the SMBJ20A by MDD. Check their datasheets: a part that fits the footprint may still differ in its ratings.
