Is there a KiCad symbol and footprint for the SM4T68CAY?
Yes. The symbol is Device:D_TVS 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 SM4T68CAY?
SMA(DO-214AC), with 2 pins. Its footprint is drawn on this page.
Where is the SM4T68CAY datasheet?
STMicroelectronics publishes it: the Datasheet link on this page opens it.
Where can I order the SM4T68CAY?
JLCPCB lists it as part C1974137, with 31 in stock; the sellers' links on this page open their listings.
What can replace the SM4T68CAY?
Parts like it in the library: the SMAJ58A by hongjiacheng, the SMAJ58CA by hongjiacheng, the SMAJ58A by GOODWORK and the SMAJ58A by MDD. Check their datasheets: a part that fits the footprint may still differ in its ratings.
