Is there a KiCad symbol and footprint for the UESD3.3D?
Yes. The symbol is EasyEDA_Cloud:UESD3.3DT5G and the footprint Package_TO_SOT_SMD:SOT-723, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the UESD3.3D?
SOT-723, with 3 pins. Its footprint is drawn on this page.
Where is the UESD3.3D datasheet?
onsemi publishes it: the Datasheet link on this page opens it.
Where can I order the UESD3.3D?
JLCPCB lists it as part C233435, with 2,683 in stock; the sellers' links on this page open their listings.
What can replace the UESD3.3D?
Parts like it in the library: the ESD7C3.3DT5G-MS by MSKSEMI, the ESD7C3.3D by onsemi, the ESD7C3.3DT5G by TECH PUBLIC and the SZUESD3.3D by onsemi. Check their datasheets: a part that fits the footprint may still differ in its ratings.
