Is there a KiCad symbol and footprint for the MM3Z43VB?
Yes. The symbol is Diode:MM3Zxx and the footprint Diode_SMD:D_SOD-323F, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the MM3Z43VB?
SOD-323FL, with 2 pins. Its footprint is drawn on this page.
Where is the MM3Z43VB datasheet?
onsemi publishes it: the Datasheet link on this page opens it.
Where can I order the MM3Z43VB?
JLCPCB lists it as part C891620, with 16 in stock; the sellers' links on this page open their listings.
What can replace the MM3Z43VB?
Parts like it in the library: the BZT52B43LS-TP by Micro Commercial Components, the BZX84J-B43 by Nexperia, the BZX384-B43 by Nexperia and the MM3Z43-TD by TDSEMIC. Check their datasheets: a part that fits the footprint may still differ in its ratings.
