Is there a KiCad symbol and footprint for the MMSZ20?
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 MMSZ20?
SOD-123, with 2 pins. Its footprint is drawn on this page.
Where is the MMSZ20 datasheet?
onsemi publishes it: the Datasheet link on this page opens it.
Where can I order the MMSZ20?
JLCPCB lists it as part C463086, with 373 in stock; the sellers' links on this page open their listings.
What can replace the MMSZ20?
Parts like it in the library: the MMSZ5250B by onsemi, the BZT52C20Q by JSMSEMI, the MM1Z20 by Shandong Jingdao Microelectronics and the MM1Z20 by CBI. Check their datasheets: a part that fits the footprint may still differ in its ratings.
