Questions

Is there a KiCad symbol and footprint for the SML4746A?

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 SML4746A?

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

Where is the SML4746A datasheet?

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

Where can I order the SML4746A?

JLCPCB lists it as part C5365485, with 1,066 in stock; the sellers' links on this page open their listings.

What can replace the SML4746A?

Parts like it in the library: the SZA18A by Leshan Radio (LRC), the 1SMA5931B by onsemi, the SML4746A-E3 by Vishay Intertechnology and the SMAZ18 by Diodes Incorporated. Check their datasheets: a part that fits the footprint may still differ in its ratings.
