Is there a KiCad symbol and footprint for the SM4T30CAY?
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 SM4T30CAY?
SMA(DO-214AC), with 2 pins. Its footprint is drawn on this page.
Where is the SM4T30CAY datasheet?
STMicroelectronics publishes it: the Datasheet link on this page opens it.
Where can I order the SM4T30CAY?
JLCPCB lists it as part C1975788, with 3,572 in stock; the sellers' links on this page open their listings.
What can replace the SM4T30CAY?
Parts like it in the library: the SMAJ26A by hongjiacheng, the SMAJ26CA by GOODWORK, the SMAJ26A/TR13 by Brightking and the SMAJ26A by UMW. Check their datasheets: a part that fits the footprint may still differ in its ratings.
