Is there a KiCad symbol and footprint for the MMSZ15?
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 MMSZ15?
SOD-123, with 2 pins. Its footprint is drawn on this page.
Where is the MMSZ15 datasheet?
onsemi publishes it: the Datasheet link on this page opens it.
Where can I order the MMSZ15?
JLCPCB lists it as part C27754, with 15,491 in stock; the sellers' links on this page open their listings.
What can replace the MMSZ15?
Parts like it in the library: the BZT52C15 by MDD, the MMSZ5245B by onsemi, the BZT52C15Q by JSMSEMI and the BZT52C15 by Shikues. Check their datasheets: a part that fits the footprint may still differ in its ratings.
