Is there a KiCad symbol and footprint for the SZMMBZ33VAL?
Yes. The symbol is EasyEDA_Cloud:NUP2105LT1G_C5261087 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 SZMMBZ33VAL?
SOT-23, with 3 pins. Its footprint is drawn on this page.
Where is the SZMMBZ33VAL datasheet?
onsemi publishes it: the Datasheet link on this page opens it.
Where can I order the SZMMBZ33VAL?
JLCPCB lists it as part C719773, with 43,981 in stock; the sellers' links on this page open their listings.
What can replace the SZMMBZ33VAL?
Parts like it in the library: the MMBZ33VAL by onsemi, the MMBZ33VAL by DOWO, 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.
