Is there a KiCad symbol and footprint for the ASD18C?
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 ASD18C?
SOD-323, with 2 pins. Its footprint is drawn on this page.
Where is the ASD18C datasheet?
Applied Power publishes it: the Datasheet link on this page opens it.
Where can I order the ASD18C?
JLCPCB lists it as part C712128, with 0 in stock; the sellers' links on this page open their listings.
What can replace the ASD18C?
Parts like it in the library: the UDD32C03L01 by Brightking, the H3V3SD3B by hongjiacheng, the H3V3HD3U by hongjiacheng and the PESD3V3L1BA by UMW. Check their datasheets: a part that fits the footprint may still differ in its ratings.
