ESD Protection for Analog video signals

Other Parts Discussed in Thread: TPD1E01B04, TPD2E001

Hi,

For Analog video signals ( CVBS video signals, HD RGB signals), whether we can use TPD1E01B04DPLT for ESD Protection?

Regards

    Madhu-

    TPD1E01B04 has a low enough capacitance that it should support any analog video signal. As long as the maximum signal swing of the video signal stays within the standoff region of the TPD1E01B04 (-3.6V < Vsignal < 3.6V), then the device should do an excellent job protecting your device. If the signal swing will go higher than that, let me know what the maximum signal voltage (and the signal speed) is and I can offer a recommendation for a different part.

    Thanks,
    Alec

    Hi Alec,

    Thanks for the answer.

    The analog signal stays within the standoff range always. In earlier designs, for the same analog signals, we had used TPD2E001DRLR.
    Now we are going for TPD1E01B04 to make the PCB routing easy. Functionally, Is there any difference between these two ICs?

    Thanks & Regards

    Madhu-

    For your application, it sounds ike the TPD1E01B04 should be able to replace the TPD2E001. The TPD1E01B04 should be an improvement on the older device in nearly every aspect, and should actually be improved clamping given that the breakdown voltage is a much better fit for your application!

    Thanks,
    Alec
