Hi,all

Let me ask a question about TPD4E1U06.

Absolute maximum ratings is written on the datasheet ,however,could you bring any evaluation result for reaching breaking ?

Customer seems to wolld like to know whether it is destroied by charged 100m LAN cable .

best regards.

    Taichi,

    Thank you for your inquiry. The tests performed to evaluate the absolute maximum ratings for surge are tightly controlled according to the IEC 61000-4-5. A charged 100 m LAN cable will have a slower rise time than, say, 10 m of the same cable, but a longer discharge time. The discharge current will be a function of the voltage the cable is charged to. Can you let me know what that is?

    Thanks,

    Hi,guy

    Thank you for reply.


    I think to need conveying specific cable information , however , what infromation do you need ?


    Category such as CATx , form such as flat or model number?

    Mr.Guy
    I heard that test conditon is connecting four charged 1000V/500pF capacitors in series to the device by my customer.

    This voltage will present 500-A of current per IEC 61000-4-5 specification. We do not have a device to sustain such a strong strike. Gas Discharge Tubes are gerally used for protection against this.

    Hi,Mr.Guy

    Thank you for reply.

    I confirmed IEC61000-4-5 and understood that 1000V/500A is level2 .

     

    My customer is using SR2.8TCT for now , it has IEC 61000-4-5 (Lightning) 12A (8/20μs).

    My customer test condition is IEC 61000-4-5 level4(4000V/2000A) , I heard that SR2.8TCT could endure the test , however ,

    I think that SR2.8TCT can't endure the test on the issue of peak pulse current rating.

     

    Is there a diffrence between IEC 61000-4-5 current spec and peak pulse current of ESD protection device ?

     

    I am looking forward to your reply.

    Taichi.

    Taichi,

    Sorry for the late reply! If the "peak pulse current of ESD protection device" is specified for IEC 61000-4-5 then there would be no difference. If it is specified for any other standard, then yes, there would be. Do you have a specific example in mind?
