Description
The SMFJ series is designed specifically to protect sensitive electronic equipment from voltage transients induced by lightning
and other transient voltage events. SOD-123FL package is 50% smaller in footprint when compare to SMA package and
deliverying low height profile (1.1mm) in the industry.
