Overview

The SMBJ48A is an uncategorised made by RealChip in a SMB package with 2 pins. -65℃~+150℃ 1 1uA 390pF 48V 58.9V 600W@10/1000us 7.8A@10/1000us 77.4V 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. 79 are in stock at JLCPCB (part C6937322).

Questions

Is there a KiCad symbol and footprint for the SMBJ48A?

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 SMBJ48A?

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

Where is the SMBJ48A datasheet?

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

Where can I order the SMBJ48A?

JLCPCB lists it as part C6937322, with 79 in stock; the sellers' links on this page open their listings.

What can replace the SMBJ48A?

Parts like it in the library: the SMBJ48A by hongjiacheng, the SMBJ48A by TECH PUBLIC, the SMBJ48A by TDD and the SMBJ48A by YFW. Check their datasheets: a part that fits the footprint may still differ in its ratings.
