Questions
Is there a KiCad symbol and footprint for the UESD54B?
Yes. The symbol is Device:D_TVS and the footprint Diode_SMD:D_SOD-523, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the UESD54B?
SOD-523, with 2 pins. Its footprint is drawn on this page.
Where is the UESD54B datasheet?
Union Semiconductor publishes it: the Datasheet link on this page opens it.
Where can I order the UESD54B?
JLCPCB lists it as part C5180318, with 74 in stock; the sellers' links on this page open their listings.
What can replace the UESD54B?
Parts like it in the library: the ESD5Z5.0T1G-MS by MSKSEMI, the ESD5Z5.0 by onsemi, the ESD5B5.0S by onsemi and the H5VUD5BB by hongjiacheng. Check their datasheets: a part that fits the footprint may still differ in its ratings.
