Is there a KiCad symbol and footprint for the MMSZ39VCW?
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 MMSZ39VCW?
SOD-123, with 2 pins. Its footprint is drawn on this page.
Where is the MMSZ39VCW datasheet?
FMS publishes it: the Datasheet link on this page opens it.
Where can I order the MMSZ39VCW?
JLCPCB lists it as part C163777, with 0 in stock; the sellers' links on this page open their listings.
What can replace the MMSZ39VCW?
Parts like it in the library: the MM1Z39 by CBI, the BZT52C39 by MDD, the BZT52-B39X by Nexperia and the MMSZ39VBW by Tak Cheong. Check their datasheets: a part that fits the footprint may still differ in its ratings.
