Hey, guys

I need to ask a question to those of you more knowledgeable in electronics. I'm looking at this TVS family datasheet. What are those numbers? Clamping voltages, but what does 10/1000 uS and 8/20 uS time periods mean in this context?

Thank you!

Hey CD,

The info you seek is in the datasheet:


  • @10μs the TVS is 100%, Ipp, conducting.
  • @1000μs the TVS is 50% Ipp

Hope this is what your'e looking for?

Best wishes, stay safe and well,

Yes, I think so. Thanks, man!

 a note from Vishay

The breakdown voltage is the voltage at which the device goes into avalanche breakdown, and is measured at a specified current on the datasheet. The clamping voltage appears across the TVS at the specified peak pulse current rating

The great Nikola Tesla:

Ere many generations pass, our machinery will be driven by a power obtainable at any point of the universe. This idea is not novel. Men have been led to it long ago go by instinct or reason. It has been expressed in many ways, and in many places, in the history of old and new. We find it in the delightful myth of Antheus, who drives power from the earth; we find it among the subtle speculations of one of your splendid mathematicians, and in many hints and statements of thinkers of the present time. Throughout space there is energy. Is this energy static or kinetic? If static, our hopes are in vain; if kinetic - and this we know it is for certain - then it is a mere question of time when men will succeed in attaching their machinery to the very wheelwork of nature.
