Device Ratings and Specifi cations Any Single Section
NOTES: 1. Tested to IEC61000-4-2 Human Body Model (HBM) discharge test circuit.
2. Direct discharge to device terminals (IEC preffered test method).
3. Corona discharge through air (represents actual ESD event)
4. Capacitance may be customized, contact Sales.

Peak Current and Energy Derating Curve
For applications exceeding 125ºC ambient temperature, the
peak surge current and energy ratings must be reduced.
