Is there a KiCad symbol and footprint for the MM1Z27?
Yes. The symbol is Device:D_Zener and the footprint Diode_SMD:D_SOD-123, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the MM1Z27?
SOD-123, with 2 pins. Its footprint is drawn on this page.
Where is the MM1Z27 datasheet?
HT publishes it: the Datasheet link on this page opens it.
Where can I order the MM1Z27?
JLCPCB lists it as part C746237, with 0 in stock; the sellers' links on this page open their listings.
What can replace the MM1Z27?
Parts like it in the library: the BZT52C27 by MDD, the BZT52C27Q by JSMSEMI, the MM1Z27 by CBI and the MM1ZB27 by CBI. Check their datasheets: a part that fits the footprint may still differ in its ratings.
