Is there a KiCad symbol and footprint for the SD05?
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 SD05?
SOD-323, with 2 pins. Its footprint is drawn on this page.
Where is the SD05 datasheet?
MDD publishes it: the Datasheet link on this page opens it.
Where can I order the SD05?
JLCPCB lists it as part C502527, with 945,865 in stock; the sellers' links on this page open their listings.
What can replace the SD05?
Parts like it in the library: the H5VLD3B by hongjiacheng, the PESD5V0S1BA by HXY MOSFET, the PESD5V0S1BA by TECH PUBLIC and the H5VSD3B by hongjiacheng. Check their datasheets: a part that fits the footprint may still differ in its ratings.
Which open-source boards use the SD05?
20 boards in 18 repositories on GitHub; the most starred are listed on this page, with their KiCad files.
