Is there a KiCad symbol and footprint for the MM1Z68?
Yes. The symbol is Device:D_Zener and the footprint Diode_SMD:D_SOD-123, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the MM1Z68?
SOD-123, with 2 pins. Its footprint is drawn on this page.
Where is the MM1Z68 datasheet?
STMicroelectronics publishes it: the Datasheet link on this page opens it.
Where can I order the MM1Z68?
JLCPCB lists it as part C107450, with 1,004 in stock; the sellers' links on this page open their listings.
What can replace the MM1Z68?
Parts like it in the library: the BZT52C68 by NH, the MMSZ5266B by onsemi, the BZT52C68W by CBI and the MM1Z68 by CBI. Check their datasheets: a part that fits the footprint may still differ in its ratings.
