SMF5.0A_12 Datasheet, PDF (1/6 Pages) Littelfuse – Transient Voltage Suppression Diodes

SMF Series
Transient Voltage Suppression Diodes
Surface Mount – 200W > SMF Series
RoHS
TVS Diode Arrays (SPA^™Family of Products)
Description
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.
