Overview
The ZMM51 is a zener Diode made by STMicroelectronics in a LL-34 package with 2 pins. 1 Independent 100nA@39V 125Ω 48V~54V 500mW 51V 700Ω LL-34 Zener Diodes ROHS.
PCBKit's library has its KiCad symbol (Diode:ZMMxx, from KiCad's library) and its footprint (Diode_SMD:D_MiniMELF, from KiCad's library), ready for a KiCad board. JLCPCB lists it (part C8086).

Is there a KiCad symbol and footprint for the ZMM51?
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 ZMM51?
LL-34, with 2 pins. Its footprint is drawn on this page.
Where is the ZMM51 datasheet?
STMicroelectronics publishes it: the Datasheet link on this page opens it.
Where can I order the ZMM51?
JLCPCB lists it as part C8086, with 0 in stock; the sellers' links on this page open their listings.
What can replace the ZMM51?
Parts like it in the library: the ZMM55C51 by FUXINSEMI, the ZMM5262B by JSMSEMI, the BZV55C51 by LGE and the ZMM51 by Zhengxin. Check their datasheets: a part that fits the footprint may still differ in its ratings.
