Questions

Is there a KiCad symbol and footprint for the ZMM5251B?

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 ZMM5251B?

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

Where is the ZMM5251B datasheet?

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

Where can I order the ZMM5251B?

JLCPCB lists it as part C118703, with 10 in stock; the sellers' links on this page open their listings.

What can replace the ZMM5251B?

Parts like it in the library: the ZMM22V by JSMSEMI, the ZMM22V by YONGYUTAI, the BZV55C22 by LGE and the ZMM22-MS by MSKSEMI. Check their datasheets: a part that fits the footprint may still differ in its ratings.
