SIDACtor (R) Protection Thyristors
LCAS Protection
Asymmetrical Multiport Series - MS-013
Description Asymmetrical Multiport Series are SIDACtor(R) 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. Features and Benefits Low voltage overshoot Low on-state voltage Agency Approvals
Agency Agency File Number E133083
Replaces four discrete devices Two-port protection LCAS specific tip and ring thresholds
Does not degrade with use Fails short circuit when surged in excess of ratings
