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.
