Questions

Is there a KiCad symbol and footprint for the ZMM3V3-M?

Yes. The symbol is Diode:ZMMxx and the footprint Diode_SMD:D_MiniMELF, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the ZMM3V3-M?

LL-34, with 2 pins. Its footprint is drawn on this page.

Where is the ZMM3V3-M datasheet?

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

Where can I order the ZMM3V3-M?

JLCPCB lists it as part C8056, with 0 in stock; the sellers' links on this page open their listings.

What can replace the ZMM3V3-M?

Parts like it in the library: the ZMM3V3PF-M by STMicroelectronics, the ZMM3V3 by HXY MOSFET, the BZV55C3V3 by LGE and the ZMM3V3 by Slkor. Check their datasheets: a part that fits the footprint may still differ in its ratings.

Which open-source boards use the ZMM3V3-M?

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