Overview
The CSH18CB is an ESD And Surge Protection made by SCME in a SOD-323 package with 2 pins.
PCBKit's library has its KiCad symbol (Device:D_TVS, from KiCad's library) and its footprint (Diode_SMD:D_SOD-323, from KiCad's library), ready for a KiCad board. JLCPCB lists it (part C7419227).

Is there a KiCad symbol and footprint for the CSH18CB?
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 CSH18CB?
SOD-323, with 2 pins. Its footprint is drawn on this page.
Where is the CSH18CB datasheet?
SCME publishes it: the Datasheet link on this page opens it.
Where can I order the CSH18CB?
JLCPCB lists it as part C7419227, with 0 in stock; the sellers' links on this page open their listings.
What can replace the CSH18CB?
Parts like it in the library: the ESDBL18VD3N by BORN, the SDD32C18L01 by Brightking, the CDSOD323-T18LC by TECH PUBLIC and the TPGC18C by TECH PUBLIC. Check their datasheets: a part that fits the footprint may still differ in its ratings.
