Semilab Lateral MOSFET SPICE Models ALF08N20V, ALF08P20V, ALF16N20W, ALF16P20W

[xsipower]

Hello All,

As many on this forum, I could not find good models of Lateral Mosfets. The models from Exicon are not accurate; Profusion and Semelab don't give out Models. So using Intusoft SpiceMod5 software, the data sheets provided by Semelab, I generated models that I verified through SPICE simulation match the datasheets. I'm sorry I don't have the physical parts themselves to compare to the datasheets. The models should match the datasheets quite well for linear operation. The switching characteristics are not accurate since the data sheets give little detail as to the method used to determine the Ton and Toff values.

Use these models if you wish for DIY simulations. I do not claim any warranty that these models match the actual devices. They are provided AS IS. Please give me feedback if you like.

Cheers,

Leslie

[Osvaldo de Banfield]

Good job, guy. Some time ago I published in this forum my own models for 2SK117 and other JFETs according their IDSS Toshiba's classification.

Cordially, Osvaldo.

Thanks Leslie & Osvalaldo
Now I will read/absorb B. Cordell book, section 19.9 on how to use the subcircuit in LTspice.

 

[Krisfr]

Would someone be kind enough to indicate a thread or post that shows the BEST way to add these to LTSpice for use.

Thanks

There is an LTspice Thread for beginners. It has been running for a couple of years.
