NOTES:

1. Tested to IEC61000-4-2 Human Body Model (HBM) discharge test circuit. See explanation of Terms on page 7.

2. Direct discharge to device terminals (IEC preffered test method). See figure 2.

3. Corona discharge through air (represents actual ESD event)

4. Capacitance may be customized, contact Sales.
