Questions

Is there a KiCad symbol and footprint for the SMAJ33A?

Yes. The symbol is Diode:SMAJ33A and the footprint Diode_SMD:D_SMA, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the SMAJ33A?

SMAG, with 2 pins. Its footprint is drawn on this page.

Where is the SMAJ33A datasheet?

Jiangsu Changjing Electronics Technology (CJ) publishes it: the Datasheet link on this page opens it.

Where can I order the SMAJ33A?

JLCPCB lists it as part C5294337, with 9,641 in stock; the sellers' links on this page open their listings.

What can replace the SMAJ33A?

Parts like it in the library: the SMAJ33CA by MDD, the SMAJ33CA by hongjiacheng, the SMAJ33CA by GOODWORK and the SMAJ33CA by 晶导微电子. Check their datasheets: a part that fits the footprint may still differ in its ratings.
