Transient Voltage Suppressors (TVS)
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 delivering low height profile (1.1mm) in the
industry.
