CM1236
Performance Information
Graphical Comparison and Test Setup
Figure 5 shows that the CM1236 (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 6 also indicates that the DUP/ASIC protected
by the CM1236 dissipates less energy than a standard ESD protection device. This data was derived using the test setups shown
in Figure 7.
