Questions

Is there a KiCad symbol and footprint for the MM3Z18VB?

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 MM3Z18VB?

SOD-323FL, with 2 pins. Its footprint is drawn on this page.

Where is the MM3Z18VB datasheet?

onsemi publishes it: the Datasheet link on this page opens it.

Where can I order the MM3Z18VB?

JLCPCB lists it as part C891584, with 197 in stock; the sellers' links on this page open their listings.

What can replace the MM3Z18VB?

Parts like it in the library: the MM3Z18BW by Shandong Jingdao Microelectronics, the BZT52B18LS-TP by Micro Commercial Components, the PZU18B1 by Nexperia and the PZU18B2 by Nexperia. Check their datasheets: a part that fits the footprint may still differ in its ratings.

Which open-source boards use the MM3Z18VB?

4 boards in 2 repositories on GitHub; the most starred are listed on this page, with their KiCad files.
