Questions

Is there a KiCad symbol and footprint for the SM30T68CAY?

Yes. the footprint Diode_SMD:D_SMC, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the SM30T68CAY?

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

Where is the SM30T68CAY datasheet?

STMicroelectronics publishes it: the Datasheet link on this page opens it.

Where can I order the SM30T68CAY?

JLCPCB lists it as part C5336205, with 10 in stock; the sellers' links on this page open their listings.

What can replace the SM30T68CAY?

Parts like it in the library: the SMCJ58CA by TECH PUBLIC, the SMCJ58CA by ShunYe, the SMDJ58CA by TECH PUBLIC and the SMCJ58CA by Zhengxin. Check their datasheets: a part that fits the footprint may still differ in its ratings.
