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.
