Is there a KiCad symbol and footprint for the MM3Z18B?
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 MM3Z18B?
SOD-323, with 2 pins. Its footprint is drawn on this page.
Where is the MM3Z18B datasheet?
STMicroelectronics publishes it: the Datasheet link on this page opens it.
Where can I order the MM3Z18B?
JLCPCB lists it as part C7464250, with 3,095 in stock; the sellers' links on this page open their listings.
What can replace the MM3Z18B?
Parts like it in the library: the MM3Z18-TD by TDSEMIC, the BZX384-B18 by Nexperia, the BZX384-B18-JSM by JSMSEMI and the BZT52B18S by MDD. Check their datasheets: a part that fits the footprint may still differ in its ratings.
