Questions

Is there a KiCad symbol and footprint for the MMSZ5246B?

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 MMSZ5246B?

SOD-123, with 2 pins. Its footprint is drawn on this page.

Where is the MMSZ5246B datasheet?

Diodes Incorporated publishes it: the Datasheet link on this page opens it.

Where can I order the MMSZ5246B?

JLCPCB lists it as part C74710, with 15,434 in stock; the sellers' links on this page open their listings.

What can replace the MMSZ5246B?

Parts like it in the library: the BZT52C16 by GOODWORK, the BZT52C16 by Jiangsu Changjing Electronics Technology (CJ), the BZT52C16 by MDD and the BZT52C16 by TWGMC. Check their datasheets: a part that fits the footprint may still differ in its ratings.
