Hi Dan,
there are basically two common methods to determine the clamping voltage:
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,
Joost
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.
