Is there a KiCad symbol and footprint for the ESDA25W?
Yes. The symbol is Diodes:Diode TVS Uni-Directionnal x2 C1A3_C2A3 and the footprint Package_TO_SOT_SMD:SOT-323_SC-70, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the ESDA25W?
SOT-323-3L, with 3 pins. Its footprint is drawn on this page.
Where is the ESDA25W datasheet?
STMicroelectronics publishes it: the Datasheet link on this page opens it.
Where can I order the ESDA25W?
JLCPCB lists it as part C2935152, with 3,320 in stock; the sellers' links on this page open their listings.
What can replace the ESDA25W?
Parts like it in the library: the PESD1CAN-UX by Nexperia, the PESD1CAN-UX by TECH PUBLIC, the TPESD24BC3 by TECH PUBLIC and the TPPESD1CAN-U by TECH PUBLIC. Check their datasheets: a part that fits the footprint may still differ in its ratings.
Which open-source boards use the ESDA25W?
32 boards in 29 repositories on GitHub; the most starred are listed on this page, with their KiCad files.
