Is there a KiCad symbol and footprint for the MM3Z75?
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 MM3Z75?
SOD-323, with 2 pins. Its footprint is drawn on this page.
Where is the MM3Z75 datasheet?
CBI publishes it: the Datasheet link on this page opens it.
Where can I order the MM3Z75?
JLCPCB lists it as part C51315412, with 2,900 in stock; the sellers' links on this page open their listings.
What can replace the MM3Z75?
Parts like it in the library: the BZX384-C75 by Nexperia, the MM3Z75-TD by TDSEMIC, the BZT52C75S by Yangzhou Yangjie Electronic Technology and the MM3Z75B by Shandong Jingdao Microelectronics. Check their datasheets: a part that fits the footprint may still differ in its ratings.
