Questions

Is there a KiCad symbol and footprint for the MMSZ3V3?

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 MMSZ3V3?

SOD-123, with 2 pins. Its footprint is drawn on this page.

Where is the MMSZ3V3 datasheet?

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

Where can I order the MMSZ3V3?

JLCPCB lists it as part C94381, with 28,732 in stock; the sellers' links on this page open their listings.

What can replace the MMSZ3V3?

Parts like it in the library: the BZT52C3V3 by MDD, the MMSZ5226B by onsemi, the BZT52-B3V3J by Nexperia and the MM1Z3V3 by Shandong Jingdao Microelectronics. Check their datasheets: a part that fits the footprint may still differ in its ratings.
