Questions
Is there a KiCad symbol and footprint for the MMSZ5221B?
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 MMSZ5221B?
SOD-123, with 2 pins. Its footprint is drawn on this page.
Where is the MMSZ5221B datasheet?
MDD publishes it: the Datasheet link on this page opens it.
Where can I order the MMSZ5221B?
JLCPCB lists it as part C2993558, with 2,820 in stock; the sellers' links on this page open their listings.
What can replace the MMSZ5221B?
Parts like it in the library: the BZT52C2V4 by MDD, the MMSZ5221B by onsemi, the MM1Z2V4 by CBI and the BZT52C2V4 by Galaxy Microelectronics. Check their datasheets: a part that fits the footprint may still differ in its ratings.
