Questions

Is there a KiCad symbol and footprint for the ST34BF?

Yes. The symbol is Device:D_Schottky and the footprint EasyEDA_Cloud:SMBF_L4.3-W3.6-LS5.3-RD, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the ST34BF?

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

Where is the ST34BF datasheet?

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

Where can I order the ST34BF?

JLCPCB lists it as part C414005, with 0 in stock; the sellers' links on this page open their listings.

What can replace the ST34BF?

Parts like it in the library: the SM540BF by Leshan Radio (LRC), the SS54BF by Shikues, the SS54BF by hongjiacheng and the SS56BF by hongjiacheng. Check their datasheets: a part that fits the footprint may still differ in its ratings.
