Default Update of all my earlier VDMOS models

Hi All,

There were typos and minor mistakes in a few of my VDMOS model updates with the new temp cos so I have fixed them and posted them all here. VDMOS - PAK2 devo
until they are rechecked, then I can use an embedded code box. Please let me know if you find any typos or bad values etc. My earlier models are still good enough for most sims.

I have updated all my earlier VDMOS models with new body diode parameters that use the new temp co parameter Trb1. This is helpful for SSR's (for SS speaker protection relays) and catch diode simulation (SOA sims).

BTW my link above has the models in both LT-IV compatible format (without the new temp co params) as well as the new LT-XVII model format. I use LT-IV but have checked my new LT-XVII model on a friends PC.

I found is an issue with LT-XVII. If you run the files with LT-IV that are save using LT-XVII the file runs but you lose all the plot information (plot data is not backward compatible). I'll try and remember to add separate plot files for LT-IV users in the above download. Rename/remove the "-IV" part but first delete the other .plt file).

Hi All, More updates completed. Now all 24 done.

I measured the Exicon lateral body diodes at 25C and 27C. They are better now. The ZVN2110G, ZVNP2110G and VN88AFD datasheets did not have any body diode info so I found the ZVNL110G and ZVP4525G are similar devices had diode plots so I used those.

Until the are re-checked all 24 the models are the 1st download on my VDMOS page here VDMOS - PAK2 devo

Hi Toni, thanks for the thanks.

Legacy LT-IV models are also available - see my PAKproject link >Spice Models>VDMOS
Thanks Ian - Nice sets of models!

Cheers,

I think you have opened a can of worms.

I fitted to the ON-Fairchild 2002 IRF150N Datasheet Fig-7 (attached) which shows 42A at Vgs=5V, which is what you read.

The Infineon-IR IRF150N Datasheet is the same as the IRF150 Datasheet (attached).

This may be an oversight on the behalf of IR by copying the old datasheet for the upgraded IRFP150N. If so use the ON-Semi model as I supplied.

If you want a model to match the IRFP150N that you are using you need to do a test to see which of the two IRFP150N models you need.

BTW attached is your jig with my IRFP150N and now with the Infineon IRFP150. You can see the Id for the IRFP150 is the same as the MODPLEX subcircuit.

Also in the jig I added a convenient way to convert my IRFP150N back to the IRFP150 using the 'ako:' statement below:
.model IRFP150 ako:IRFP150N Kp=22 Rs=30m
Add this to your circuit and you can enable it to select the IRFP150 or the Infineon/MODPLEX IRF150N) for DC conditions (the AC property remains the faster ON-Semi IRFP150N).

BTW I ammended the model code in the attached to better match the datasheets I used.

Hi UltimateX86,

I tried plotting your points with the IRFP150N model at 40 deg.C.

Setting Vto=3.9 is close enough. See attached plots. Red is the IRFP150N.

You don't have enough points to see if the model is OK at higher current so I suggest you assume my model from the ON-Semi datasheet is correct (unless you find your simulations are quite different from measurements).

I also tried scaling the IRFP150N model area and found a closer fit to your data with an area of 0.15 of the original model. See 2nd attachment.

If scaling is actually necessary to fit your data then either
1) your measured data is not good (maybe not isothermal enough using microsecond pulses like the datasheets), or
2) the device is not an IRFP150N (maybe a fake chip).

Cheers,

hi,

My infineon mosfet comes from mouser, but indeed I do not have the same hardware as used in the datasheet

Just an servo opamp to keep the current selected and a thermocouple to take the value at 40
