Axial Leaded – 500W > SA series
SA Series
Please refer to http://www.Littelfuse.com/series/SA.html for current information.
SA Series
The SA Series is designed specifically to protect sensitive
electronic equipment from voltage transients induced by
lightning and other transient voltage events.
Description
SA Series
TVS devices are ideal for the protection of I/O interfaces,
VCC bus and other vulnerable circuits used in telecom,
computer, industrial and consumer electronic applications.
