Littelfuse, Inc. Overvoltage Protection - SIDACtor® Protection Thyristors - Connectivity SIDACtor® Protection Thyristors - Series: Bxxx1u_4 - B1161UA4 B1161UA4

The Dual Port Negative Battrax® Series are programmable SIDACtor® devices designed to protect SLICs (Subscriber Line Interface Circuit) from damaging overvoltage transients. Dual port protection is provided by a programmable device that is referenced to a negative voltage source while internal diodes provide protection from positive surge events. Low voltage overshoot Low on-state voltage Does not degrade with use Fails short circuit when surged in excess of ratings Dual-port protection Gate trigger tracking device Integrated diode for positive voltage surges
