Is there a KiCad symbol and footprint for the ZMM33-M?
Yes. The symbol is Device:D_Zener 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 ZMM33-M?
LL-34, with 2 pins. Its footprint is drawn on this page.
Where is the ZMM33-M datasheet?
STMicroelectronics publishes it: the Datasheet link on this page opens it.
Where can I order the ZMM33-M?
JLCPCB lists it as part C2840150, with 0 in stock; the sellers' links on this page open their listings.
What can replace the ZMM33-M?
Parts like it in the library: the ZMM33V by JSMSEMI, the ZMM33 by DIOTEC, the BZV55C33 by LGE and the ZMM55-C33_R1_10001 by PANJIT International. Check their datasheets: a part that fits the footprint may still differ in its ratings.
