Questions

Is there a KiCad symbol and footprint for the ZMM5256B?

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 ZMM5256B?

MiniMELF, with 2 pins. Its footprint is drawn on this page.

Where is the ZMM5256B datasheet?

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

Where can I order the ZMM5256B?

JLCPCB lists it as part C118708, with 0 in stock; the sellers' links on this page open their listings.

What can replace the ZMM5256B?

Parts like it in the library: the ZMM30V by JSMSEMI, the ZMM5256B by JSMSEMI, the BZV55C30 by LGE and the BZV55C30-MS by MSKSEMI. Check their datasheets: a part that fits the footprint may still differ in its ratings.
