Overview
The MM1W12 is a zener Diode made by STMicroelectronics in a SOD-123FL package with 2 pins.
PCBKit's library has its KiCad symbol (Device:D_Zener, from KiCad's library) and its footprint (Diode_SMD:D_SOD-123F, from KiCad's library), ready for a KiCad board. 888 are in stock at JLCPCB (part C7464243).

Is there a KiCad symbol and footprint for the MM1W12?
Yes. The symbol is Device:D_Zener and the footprint Diode_SMD:D_SOD-123F, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the MM1W12?
SOD-123FL, with 2 pins. Its footprint is drawn on this page.
Where is the MM1W12 datasheet?
STMicroelectronics publishes it: the Datasheet link on this page opens it.
Where can I order the MM1W12?
JLCPCB lists it as part C7464243, with 888 in stock; the sellers' links on this page open their listings.
What can replace the MM1W12?
Parts like it in the library: the MM1W100L by hongjiacheng, the KDZVTR4.7B by ROHM Semiconductor, the KDZVTR24B by ROHM Semiconductor and the KDZVTR4.3B by ROHM Semiconductor. Check their datasheets: a part that fits the footprint may still differ in its ratings.
