Overview

The SMB6F70A is a TV made by STMicroelectronics in a SMB-flat package with 2 pins. -55℃~+175℃ 146V 200nA 27A@8/20us 4kW@8/20us 70V 86.1V IEC 61000-4-2、IEC 61000-4-4 TVS Unidirectional SMB-flat ESD and Surge Protection (TVS/ESD) ROHS.

PCBKit's library has its KiCad symbol (Device:D_TVS, from KiCad's library) and its footprint (EasyEDA_Cloud:SMB_L4.3-W3.6-LS5.4-RD, from EasyEDA), ready for a KiCad board. JLCPCB lists it (part C1980270).
