Part Number: TVS2700

When using the TVS2700 to protect an analogue input do you ground it to the 0V of the input circuit or to an earth point?

Hello Phil,

I would ground it to earth. You don't want the redirected current going back into your system and possibly damaging it.

Hi Matt,

Thanks for the reply. This is how I have grounded the TVS2700 on my circuit but was unsure as to what the 27V clamping voltage was with respect to. Are surges measured with respect to earth?

Regards

Phil

Hi Phil,

Yes the surges are measured with respect to earth. You can see how we conduct these tests here.
