Is there a KiCad symbol and footprint for the MMBZ33VAL?
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 MMBZ33VAL?
SOT-23, with 3 pins. Its footprint is drawn on this page.
Where is the MMBZ33VAL datasheet?
DOWO publishes it: the Datasheet link on this page opens it.
Where can I order the MMBZ33VAL?
JLCPCB lists it as part C19192541, with 5,433 in stock; the sellers' links on this page open their listings.
What can replace the MMBZ33VAL?
Parts like it in the library: the MMBZ33VAL by onsemi, the SZMMBZ33VAL by onsemi, the MMBZ33VALT116 by ROHM Semiconductor and the MMBZ33VALFHT116 by ROHM Semiconductor. Check their datasheets: a part that fits the footprint may still differ in its ratings.
