Questions

Is there a KiCad symbol and footprint for the MM3Z43?

Yes. The symbol is Device:D_Zener and the footprint Diode_SMD:D_SOD-323, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the MM3Z43?

SOD-323, with 2 pins. Its footprint is drawn on this page.

Where is the MM3Z43 datasheet?

EIC Semicon publishes it: the Datasheet link on this page opens it.

Where can I order the MM3Z43?

JLCPCB lists it as part C2978879, with 2,560 in stock; the sellers' links on this page open their listings.

What can replace the MM3Z43?

Parts like it in the library: the BZX384-B43 by Nexperia, the MM3Z43-TD by TDSEMIC, the BZX384-C43 by Nexperia and the MM3Z43 by CBI. Check their datasheets: a part that fits the footprint may still differ in its ratings.
