Questions

Is there a KiCad symbol and footprint for the MM1Z3V9?

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 MM1Z3V9?

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

Where is the MM1Z3V9 datasheet?

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

Where can I order the MM1Z3V9?

JLCPCB lists it as part C746243, with 0 in stock; the sellers' links on this page open their listings.

What can replace the MM1Z3V9?

Parts like it in the library: the BZT52C3V9 by MDD, the MMSZ4686-E3-08 by Vishay Intertechnology, the MM1Z3V9 by CBI and the MM1Z3V9 by EIC Semicon. Check their datasheets: a part that fits the footprint may still differ in its ratings.
