Is there a KiCad symbol and footprint for the STTH4R02U?
Yes. The symbol is Device:D and the footprint Diode_SMD:D_SMB, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the STTH4R02U?
SMB, with 2 pins. Its footprint is drawn on this page.
Where is the STTH4R02U datasheet?
STMicroelectronics publishes it: the Datasheet link on this page opens it.
Where can I order the STTH4R02U?
JLCPCB lists it as part C157407, with 625 in stock; the sellers' links on this page open their listings.
What can replace the STTH4R02U?
Parts like it in the library: the ES5JB by Shandong Jingdao Microelectronics, the ES5D-SMB by GOODWORK, the RS5M-SMB by GOODWORK and the ES5JB by hongjiacheng. Check their datasheets: a part that fits the footprint may still differ in its ratings.
Which open-source boards use the STTH4R02U?
4 boards in 4 repositories on GitHub; the most starred are listed on this page, with their KiCad files.
