Is there a KiCad symbol and footprint for the ES1D?
Yes. The symbol is Device:D 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 ES1D?
SMA(DO-214AC), with 2 pins. Its footprint is drawn on this page.
Where is the ES1D datasheet?
MDD publishes it: the Datasheet link on this page opens it.
Where can I order the ES1D?
JLCPCB lists it as part C445494, with 287,865 in stock; the sellers' links on this page open their listings.
What can replace the ES1D?
Parts like it in the library: the ES1J by MDD, the RS1G by MDD, the US1G by MDD and the US1J-A by FMS. Check their datasheets: a part that fits the footprint may still differ in its ratings.
Which open-source boards use the ES1D?
29 boards in 23 repositories on GitHub; the most starred are listed on this page, with their KiCad files.
