Infineon CoolMOS Spice problem

 Hello,

 i want to use an Infineon CoolMOS in a medium/high power switching application. The chip of choise is the IPD60R600E6. The spice model can be found here:

I copied the source code from the file to a new .spi file. Then i added a new Item to my schematic, a nmos4 from the analogLib. I changed the model name to IPD60R600E6 an added the spice file to the library list.

 Then i changed the pin setup in the spice file to

.SUBCKT IPD60R600E6_L0 source gate bulk drain

because in the nmos4 lib it says that Source is pin 1, Gate is pin 2 etc. The bulk contact in the spice file is not connected because in the spice model it is connected to source.

Plotting the transfer characteristic i get far too high currents in the range of kA. Even with Vgs = 1V the transistor seems to conduct with the same current... (Vth>= 2.1V)

Any idea what i did wong? Is it the correct way to use a analogLib nmos4 and change the model name? I did the same with a IRF430 MOSFET and this worked without a problem.

Thanks in advance!
