CM1235
Performance Information
Graphical Comparison and Test Setup
Figure 4 shows that the CM1235 (PicoGuard XS ESD protector) lowers the peak voltage and clamping voltage by
45% across a wide range of loading conditions in comparison to a standard ESD protection device. Figure 5 also
indicates that the DUP/ASIC protected by the CM1235 dissipates less energy than a standard ESD protection
device. This data was derived using the test setups shown in Figure 6.
