Is there a KiCad symbol and footprint for the MM3Z5B1?
Yes. The symbol is Diode:MM3Zxx 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 MM3Z5B1?
SOD-323, with 2 pins. Its footprint is drawn on this page.
Where is the MM3Z5B1 datasheet?
STMicroelectronics publishes it: the Datasheet link on this page opens it.
Where can I order the MM3Z5B1?
JLCPCB lists it as part C7464131, with 2,516 in stock; the sellers' links on this page open their listings.
What can replace the MM3Z5B1?
Parts like it in the library: the BZX384-B5V1 by Nexperia, the MM3Z5B1 by CBI, the BZX384-C5V1,115-JSM by JSMSEMI and the MM3Z5V1BW by JSMSEMI. Check their datasheets: a part that fits the footprint may still differ in its ratings.
