Is there a KiCad symbol and footprint for the ZM4731A?
Yes. The symbol is Device:D_Zener and the footprint Diode_SMD:D_MELF, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the ZM4731A?
LL-41, with 2 pins. Its footprint is drawn on this page.
Where is the ZM4731A datasheet?
STMicroelectronics publishes it: the Datasheet link on this page opens it.
Where can I order the ZM4731A?
JLCPCB lists it as part C52467, with 29 in stock; the sellers' links on this page open their listings.
What can replace the ZM4731A?
Parts like it in the library: the DL4731A by LGE, the ZM4731A by Slkor, the ZM4731APF-M by STMicroelectronics and the ZM4731A-TD by TDSEMIC. Check their datasheets: a part that fits the footprint may still differ in its ratings.
