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.

* RDUP is the emulated Dynamic Resistance (load) of the Device Under Protection (DUP).
