Overview

The SMBJ20A is an uncategorised made by RealChip in a SMB package with 2 pins. -65℃~+150℃ 1 18.6A 1uA 20V 24.5V 32.4V 390pF 600W@10/1000us TVS Unidirectional SMB ESD and Surge Protection (TVS/ESD) ROHS.

PCBKit's library has its KiCad symbol (Diodes:Diode TVS Uni-Directional, from CERN's library) and its footprint (Diode_SMD:D_SMB, from KiCad's library), ready for a KiCad board. 24 are in stock at JLCPCB (part C6937300).

Questions

Is there a KiCad symbol and footprint for the SMBJ20A?

Yes. The symbol is Diodes:Diode TVS Uni-Directional 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?

SMB, with 2 pins. Its footprint is drawn on this page.

Where is the SMBJ20A datasheet?

RealChip publishes it: the Datasheet link on this page opens it.

Where can I order the SMBJ20A?

JLCPCB lists it as part C6937300, with 24 in stock; the sellers' links on this page open their listings.

What can replace the SMBJ20A?

Parts like it in the library: the SMBJ20A by Shenzhen JDT Fuse, the SMBJ20A by TDD, the SMB5357A by XCH and the SMBJ20A by Zhengxin. Check their datasheets: a part that fits the footprint may still differ in its ratings.
