Hi,
does anybody have the (P)SPICE models for the power mosfets BUZ900/901 and BUZ905/906 ?
Thanks

According to Charles Hanssen in an earlier thread both Magnatec and Exicon use exactly the same Semelab chips in their lateral MOSFETs, so the Exicon models should work fine.

Thank You !
... however I'm getting crazy in trying to make it work in Cadence ORCad PSPICE. I'm not really an expert of (P)SPICE.
Could you please give me some little help ?

I don't know that particular version of Spice, but please not that the models are subcircuit models, not standard MOSFET models. I don't know what implications that has in your version of Spice, but if you search the forum there shoudl at least be info on how to use them in LTSpice, which may or may not help you.
Those particular subcircuits are the ones I used with TINA and they compiled and ran perfectly. Be warned that there can be a very large device-to-device variation on BUZ90x devices (see the variation in threshold voltage shown on the data sheet) and these subcircuits don't accurately model this.
Ouroboros said:
No Spice models can handle device-to-device variations as far as I know. One simply has to use several model of the same device.
More precisely, when using subcircuits, it may be possible to vary some, but not most, parameters if using DC sweep analysis. But that is anyway only useful for Q points and similar.
