Part Number: ESD761
Other Parts Discussed in Thread: ESD751, TVS2700, TVS2200

Hi team,

Do we have ESD with 20V+ Vrwm and SOD964 package? Or could you recommend the most similar replacement? Thanks!

    Hi Kailun,

    Unfortunately, we do not have a pin-to-pin replacement with a SOD964 package. We do have a leadless package with similar dimensions with the ESD751, which is a SOD523 (1.6mm x .08mm). 

    Do you have any more information on other requirements, such as channel count, clamping voltage, etc? TI offers many 20+ Vrwm devices, and more information will help us determine the best fit for your application.

    Best Regards,

    Josh Prushing

    Hi Kailun, 

    Understood, thanks for sharing that information. Is there any way you could share the GPN/OPN of the competitor device they have chosen? 

    Best Regards,
