Unique Snapback Characteristics of XClampR® TVS

The snapback characteristics of the XClampR® TVS make differences to a conventional TVS at breakdown and clamping operation. Snapback is initiated (triggered) by a small reverse leakage current at a certain voltage and avalanche operating at a sufficiently large voltage applied across the cathode and anode. Clamping voltage is lower than the initial breakdown voltage and it can make a higher clamping current capability than a conventional TVS. The clamping voltage of a conventional TVS is linearly raised after breakdown, but the clamping voltage of the XClampR TVS is lower than the breakdown voltage and it can make a higher clamping capability than the same package type of a conventional TVS.
