Is there a KiCad symbol and footprint for the SA33A?
Yes. The symbol is Device:D_TVS and the footprint EasyEDA_Cloud:DO-15_BD3.1-L6.7-P10.70-D0.8-RD, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the SA33A?
DO-204AC(DO-15), with 2 pins. Its footprint is drawn on this page.
Where is the SA33A datasheet?
Littelfuse publishes it: the Datasheet link on this page opens it.
Where can I order the SA33A?
JLCPCB lists it as part C1976459, with 0 in stock; the sellers' links on this page open their listings.
What can replace the SA33A?
Parts like it in the library: the SMBJ33CA by hongjiacheng, the SMAJ33CA by MDD, the SMBJ33CA by Brightking and the SMAJ33CA by hongjiacheng. Check their datasheets: a part that fits the footprint may still differ in its ratings.
