Questions

Is there a KiCad symbol and footprint for the SML4749A?

Yes. The symbol is Device:D_Zener 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 SML4749A?

DO-214AC(SMA), with 2 pins. Its footprint is drawn on this page.

Where is the SML4749A datasheet?

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

Where can I order the SML4749A?

JLCPCB lists it as part C5365445, with 555 in stock; the sellers' links on this page open their listings.

What can replace the SML4749A?

Parts like it in the library: the SMAJ5934B-TP by Micro Commercial Components, the SMAZ24 by Diodes Incorporated, the SMA5934B by DOWO and the SMAJ5934B by DOWO. Check their datasheets: a part that fits the footprint may still differ in its ratings.
