TPD1E0B04: TPD1E0B04DPLR ESD Air Parameter

Dear Sir/Ms.

Is air discharge only 9kV? 

Competitor's spec. 

I check CL value with other vender's product.

For example. Murata LXES03AAA1 CL Lower then TPD1E0B04DPLR.

My customer search for PCIE Gen 4 ESD Protector. It's seem air gap must > 15KV.

Would you please give us some suggestion?

Best Regards,
