TVS1401: Clamping Voltage

Part Number: TVS1401

Tool/software:

Hi, Staff

Application Brief slvae72 for TI's Flat Clamp states, "... during a typical 1-kV Surge event with 25 A needed to be dissipated, the clamping voltage would be 19.4 V."
How do I find the value of 19.4 V?

I couldn't find 19.4V in the TVS1401 datasheet.

    Hi Cafain,

    The clamping voltage will be dependent on the peak current of the surge event.

    The electrical characteristics table includes clamping voltage at the max Ipp this device can handle of 30A. 

    As the peak current of the surge event goes up, so will the clamping voltage.

    This is why you are not finding the 19.4V in the datasheet since it was not characterized at an Ipp of 25A. 

    You can estimate Vclamp as follows:
