TVS2210: Inquiry regarding surge protection solution recommendations

Hi JH,

What is the resistance of the surge test? This is needed to know the exact Current expected for the strike. All standards like: 10/700us, 8/20us, 10/1000us are specified under a Current value.

Best,

Bryan

Hi Bryan,

Thank you for the prompt reply.

Here is the customer response.

- Please refer to the Telecommunication line and ground specifications below.

- The exact resistance value is not specified in the specification, and it appears to follow the ITU-T K.44 standard.

- The resistance value in the ITU-T K.44 standard appears to be 40 Ω.

- The actual peak current is estimated to be 15 kV / 40 Ω = 375 A.

Regards,

JH

Hi JH,

This is very high current, and we do not have anything close to this. Do you have a full document I can go over to review standard?
