As previously explained, the clamping voltage ratio of the XClampR® TVS is very low. This page shows a comparison of the clamping voltage ratio between XMC7K24CA and 5KASMC24A type conventional TVSs at different pulse wave form and device types. The XMC7K24CA is the first released product of the XClampR TVS series with an SMC package that has a clamping voltage ratio of 1.16 at 180 A, 1 ms half IPP (IPP/2) pulse wave form in specification and 1.33 clamping voltage ratio for 8 by 20 μs pulse wave form from 1 mA breakdown current to 584 A. The 5KASMC24A is the most similar type of conventional TVS to the XMC7K24CA, having a clamping voltage ratio of 1.35 at 1 ms half IPP (IPP/2) pulse wave form in specification and 1.55 clamping voltage ratio for 8 by 20 μs pulse wave form from 1 mA breakdown current to 584 A. By this low clamping voltage ratio, the XClampR TVS can handle a higher clamping current than a conventional TVS in the same package; the XMC7K24CA can absorb 1,200 A of 8 by 20 μs pulse wave form. This clamping current capability is almost two times the maximum clamping current of the 5KASMC24A conventional TVS.
