Is there a KiCad symbol and footprint for the ASMCJ14A-HF?
Yes. The symbol is Device:D_TVS and the footprint Diode_SMD:D_SMC, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the ASMCJ14A-HF?
DO-214AB(SMC), with 2 pins. Its footprint is drawn on this page.
Where is the ASMCJ14A-HF datasheet?
Comchip publishes it: the Datasheet link on this page opens it.
Where can I order the ASMCJ14A-HF?
JLCPCB lists it as part C20185291, with 0 in stock; the sellers' links on this page open their listings.
What can replace the ASMCJ14A-HF?
Parts like it in the library: the SMDJ14A/TR13 by Brightking, the SMCJ14A by Shandong Jingdao Microelectronics, the SMCJ14CA by Shandong Jingdao Microelectronics and the SMCJ14CA-L by Shandong Jingdao Microelectronics. Check their datasheets: a part that fits the footprint may still differ in its ratings.
