Is there a KiCad symbol and footprint for the SD15?
Yes. The symbol is Device:D_TVS and the footprint Diode_SMD:D_SOD-323, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the SD15?
SOD-323, with 2 pins. Its footprint is drawn on this page.
Where is the SD15 datasheet?
UMW publishes it: the Datasheet link on this page opens it.
Where can I order the SD15?
JLCPCB lists it as part C2931147, with 8,047 in stock; the sellers' links on this page open their listings.
What can replace the SD15?
Parts like it in the library: the H15VND3B by hongjiacheng, the PESD15VL1BA by FUXINSEMI, the H15VHD3U by hongjiacheng and the SD15C by MDD. Check their datasheets: a part that fits the footprint may still differ in its ratings.
