Is there a KiCad symbol and footprint for the MM3Z51?
Yes. The symbol is Diode:MM3Zxx 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 MM3Z51?
SOD-323, with 2 pins. Its footprint is drawn on this page.
Where is the MM3Z51 datasheet?
STMicroelectronics publishes it: the Datasheet link on this page opens it.
Where can I order the MM3Z51?
JLCPCB lists it as part C118622, with 2,218 in stock; the sellers' links on this page open their listings.
What can replace the MM3Z51?
Parts like it in the library: the MM3Z51 by FOSAN, the MM3Z51 by HT, the BZX384-B51 by Nexperia and the BZX384-C51-QX by Nexperia. Check their datasheets: a part that fits the footprint may still differ in its ratings.
