Questions
Is there a KiCad symbol and footprint for the SMBJ20A-HF?
Yes. The symbol is Device:D_TVS and the footprint Diode_SMD:D_SMB, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the SMBJ20A-HF?
SMB(DO-214AA), with 2 pins. Its footprint is drawn on this page.
Where can I order the SMBJ20A-HF?
JLCPCB lists it as part C2444139, with 0 in stock; the sellers' links on this page open their listings.
What can replace the SMBJ20A-HF?
Parts like it in the library: the SMBJ6.8CA by RUILON, the SMBJP6KE16A-TP by Micro Commercial Components, the SMBJ64A-NM by ShunYe and the BS0300N-C by Bencent. Check their datasheets: a part that fits the footprint may still differ in its ratings.
