Part Number: SN65HVD251

Which ESD Modle should I consider  "Human Body Model" or "Charged-Device Model for SN65HVD251DR below case?

There are two models as the condition of "Electrostatic discharge", "Human Body Model" and "Charged-Device Model"  on SN65HVD251DR Datasheet Page 4 6.2 "ESD Ratings".

When the connector of cable which connected to SN65HVD251DR is connected to other charged parts,  which model should I consider "Human Body Model" or "Charged-Device Model"?

Appreciate,

    Hi Taka Ishiyama,

    The type of ESD that you would want to reference for the application that you describe is CDM or charged device model. HBM is more of a handling spec and is design to stress a system or device for ESD levels that are expected during handling by an operator. Here is a good application note that discusses the various types of ESD in out data sheets:

    Please let me know what other questions you have?
