NOTES:
1. Tested to IEC-61000-4-2 Human Body Model (HBM) discharge test circuit.
2. Direct discharge to device terminals (IEC preferred test method).
3. Corona discharge through air (represents actual ESD event).
4. Capacitance may be customized, contact your Littelfuse Sales Representative.
Temperature De-rating
For applications exceeding 125oC ambient temperature, the peak surge
current and energy ratings must be reduced as shown in Figure 1.
