Rset values for IXYS IXTP01N100D

I don't know if anybody has put this info out here yet, but thought I would share it. I was in the process of setting up a few CCSs for an up coming project and decided to collect some data while I was at it. I hope you guys find this usefull the next time you go to use the IXYS IXTP01N100D. These values will get you in the ball park.

P.S. The gate stop resistors are 220 ohm Allen Bradley carbon comps.

Thanks!

Here is my result for testing a single device with 30V d-s.

It looks like there is a substantial difference between your measurement and mine. Difference due to Vds being ~3V over the bottom device in the cascode vs. 30V in my measurement?

On my measurements, I varied the B+ from 75V to 220V and it made no difference in current. The cascode appears to be fairly immuned to changes in B+ supply.

Have you tried with 2 mA too? Is there any issue with such current value?

I would use the IXTP01N100D part down to about 1 mA. For 1 mA and below I would use the LND150.

did you have Rset for LND150? can you post here please? thanks..
