Is there a KiCad symbol and footprint for the MM3Z22B?
Yes. The symbol is Device:D_Zener and the footprint Diode_SMD:D_SOD-323, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the MM3Z22B?
SOD-323, with 2 pins. Its footprint is drawn on this page.
Where is the MM3Z22B datasheet?
STMicroelectronics publishes it: the Datasheet link on this page opens it.
Where can I order the MM3Z22B?
JLCPCB lists it as part C7464251, with 2,000 in stock; the sellers' links on this page open their listings.
What can replace the MM3Z22B?
Parts like it in the library: the PDZ22B by Nexperia, the BZT52B22BS by Slkor, the MM3Z22-TD by TDSEMIC and the BZT52B22BS-TP by Micro Commercial Components. Check their datasheets: a part that fits the footprint may still differ in its ratings.
