Hi,

How to determine clamping voltage for ESD strike?

Thanks,

Hi Dan,

there are basically two common methods to determine the clamping voltage:


  • use TLP (Transmission Line Pulse) test method to determine the high-current, pulsed IV characteristics of a device. With the help of this characteristics you can determine the voltage at which a ESD discharge current at a certain current level will be clamped. You can find more details about TLP in our Infineon application note AN210.
  • use a high bandwidth oscilloscope to capture the voltage transient across an ESD device during an ESD strike from an ESD generator.


The current level of the ESD strike depends on the testing standard that you use: e.g. component-level Human Body Model standards have a current Peak of 0.67 A per kV ESD charging voltage. System Level ESD Standard (IEC61000-4-2) has a very short spike of 3.75A/kV followed by a slower discharge pulse of 2A/kV at 30ns after the start of the pulse.

Best regards,
