Hi team,
we need I-V curve to show our dynamic resistance to customer,
datasheet only have large scale.
we need a curve around same scale as below one, please support this thanks
Hi Fred,
The dynamic resistance is specified in the electrical characteristics, it was specified at 1/2 the peak surge current and the full peak surge current at 27 C.
Our TVS devices will have very similar clamping performance across the full range of surge current (40 A). They also experience very little derating over temperature.
Using the data above you can get an idea of the clamping voltage across Ipp. It only varies by about 0.5 V between a 24 A and 40 A surge (8/20us) at 27 C.
Even at 125 C, for a 35 A surge (8/20us) this device still clamps at a max of 28.35 V which is still within 1 V of the max clamping voltage of 24 A surge at 27 C.
Regards,
Sebastian
Hi Fred,
We don't have data points for less than 24 A. Also this device can only support up to 40 A of surge current per IEC61000-4-5 (8/20us). We won't have any data over 40 A since the device will fail above 40 A.
The graph is just extrapolated from the clamping voltage at different peak surge currents in the electrical characteristics.
The clamping performance of this device is very stable across the supported peak surge currents and temperature. This is why they're referred to as "flat clamp" devices.

Sebastian
