Questions
Is there a KiCad symbol and footprint for the SMBJ45A-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 SMBJ45A-HF?
SMB(DO-214AA), with 2 pins. Its footprint is drawn on this page.
Where can I order the SMBJ45A-HF?
JLCPCB lists it as part C2444194, with 0 in stock; the sellers' links on this page open their listings.
What can replace the SMBJ45A-HF?
Parts like it in the library: the SMBJ45A-QH by Bourns, the SMBJ45CA-QH by Bourns, the ATV06B450J-HF by Comchip and the ATV06B450JB-HF by Comchip. Check their datasheets: a part that fits the footprint may still differ in its ratings.
