Littelfuse A1225UC4LXX The series provides a specialized asymmetrical dual port overvoltage protection Datasheet

SIDACtor ® Protection Thyristors
LCAS Protection
Asymmetrical Multiport Series - MS-013
Description
Asymmetrical Multiport Series are SIDACtor® devices
designed to protect LCAS (Line Circuit Access Switch)
devices from damaging overvoltage transients.
The series provides a specialized asymmetrical dual port
overvoltage protection solution that enables equipment
to comply with various global requlatory standards.
