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.

5. V0402MHSxxx (0402 size devices) available as "R" packaging option only. Example: V0402MHS03NR. See Packaging and Tape and Reel sections (last page) for additional information.

For applications exceeding 125ºC ambient temperature, the

peak surge current and energy ratings must be reduced as

shown below.
