Overview

The 1N8179US is an ESD And Surge Protection made by Microchip Technology in a MELF-SQ(A) package with 2 pins. -55℃~+175℃ 120V 138V 150W@10/1000us 208V 4pF 500nA 720mA IEC 61000-4-2、IEC 61000-4-5、IEC 61000-4-4 TVS Unidirectional MELF-SQ(A) ESD and Surge Protection (TVS/ESD).

PCBKit's library has its KiCad symbol (Device:D_TVS, from KiCad's library) and its footprint (EasyEDA_Cloud:SQ-MELF_BD2.5-L5.1-RD, from EasyEDA), ready for a KiCad board. JLCPCB lists it (part C2629233).

Questions

Is there a KiCad symbol and footprint for the 1N8179US?

Yes. The symbol is Device:D_TVS and the footprint EasyEDA_Cloud:SQ-MELF_BD2.5-L5.1-RD, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the 1N8179US?

MELF-SQ(A), with 2 pins. Its footprint is drawn on this page.

Where is the 1N8179US datasheet?

Microchip Technology publishes it: the Datasheet link on this page opens it.

Where can I order the 1N8179US?

JLCPCB lists it as part C2629233, with 0 in stock; the sellers' links on this page open their listings.

What can replace the 1N8179US?

Parts like it in the library: the SMAJ120CA by DOWO, the SMAJ120A by GOODWORK, the SMAJ120CA by Diodes Incorporated and the SMAJ120A by DOWO. Check their datasheets: a part that fits the footprint may still differ in its ratings.
