Littelfuse A122-U-4L Asymmetrical Multiport Thyristors

Littelfuse A122-U-4L Asymmetrical Multiport Thyristors are SIDACtor® components 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 regulatory standards. Surge capability does not degrade after multiple surge events within limit. the asymmetrical multipart thyristors offer two-port protection and can replace four discrete components. The MS-013 package thyristors feature LCAS specific tip and ring thresholds, low voltage overshoot, low on-state voltage, and fails short circuit when surged in excess of ratings. A122-U-4L devices are RoHS compliant, Lead-free, and Halogen-free.
