There seems to be 5 different models.

I want to install an IRF510 model in

C:\programfiles\LTC\SwCADIII\lib\cmp\standard.mos.

While looking in this file, I see the model below.----

..model IRF1302 VDMOS(Rg=3 Vto=4 Rd=1.6m

Rs=1.2m Rb=2m Kp=50 Cgdmax=5n Cgdmin=1n Cgs=2n Cjo=1n Is=160p

mfg=International_Rectifier Vds=20 Ron=4m Qg=80n)

This model doesn't have the same info as the one I downloaded from the IR

site, which

seems to have 5 different models.

Is there a better model, (more similar to the one above) OR which of the

models below

should I pick MM, MD, MD1, MD2 or MD3?

Again, my goal,

I want to install an IRF510 model in

C:\programfiles\LTC\SwCADIII\lib\cmp\standard.mos.

Thanks, Mike
