Is there a KiCad symbol and footprint for the MMBZ20VAL?
Yes. The symbol is Diode:MMBZxx and the footprint Package_TO_SOT_SMD:SOT-23, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the MMBZ20VAL?
SOT-23, with 3 pins. Its footprint is drawn on this page.
Where is the MMBZ20VAL datasheet?
onsemi publishes it: the Datasheet link on this page opens it.
Where can I order the MMBZ20VAL?
JLCPCB lists it as part C153067, with 14,939 in stock; the sellers' links on this page open their listings.
What can replace the MMBZ20VAL?
Parts like it in the library: the MMBZ20VA by JSMSEMI, the MMBZ20VCL by Nexperia, the MMBZ20VCL-QR by Nexperia and the MMBZ20VAL by Diodes Incorporated. Check their datasheets: a part that fits the footprint may still differ in its ratings.
