Transient Voltage Suppression Diodes
Surface Mount – 200W > SMF Series
SMF Series
TVS Diode Arrays
(SPA
™
Family of Products)
Description
RoHS
The SMF series is designed specifically to protect sensitive
electronic equipment from voltage transients induced by
lightning and other transient voltage events.
SMF package is 50% smaller in footprint when compare
to SMA package and deliverying one of the lowest height
profiles (1.1mm) in the industry.
