Is there a KiCad symbol and footprint for the MM3Z68V?
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 MM3Z68V?
SOD-323, with 2 pins. Its footprint is drawn on this page.
Where is the MM3Z68V datasheet?
onsemi publishes it: the Datasheet link on this page opens it.
Where can I order the MM3Z68V?
JLCPCB lists it as part C891641, with 0 in stock; the sellers' links on this page open their listings.
What can replace the MM3Z68V?
Parts like it in the library: the BZX384-B68 by Nexperia, the MM3Z68 by CBI, the MM3Z68 by FOSAN and the MM3Z68 by Shandong Jingdao Microelectronics. Check their datasheets: a part that fits the footprint may still differ in its ratings.
