R-C Thermal Model Parameters  
DESCRIPTION  
The parametric values in the R-C thermal model have  
been derived using curve-fitting techniques. These  
techniques are described in "A Simple Method of  
Generating Thermal Models for a Power MOSFET"[1].  
When implemented in P-Spice, these values have  
matching characteristic curves to the Single Pulse  
Transient Thermal Impedance curves for the  
MOSFET.  
R-C values for the electrical circuit in the Foster/Tank  
and Cauer/Filter configurations are included.  
Note:  
For a detailed explanation of implementing these values in  
P-SPICE, refer to Application Note AN609 Thermal Simulations Of  
Power MOSFETs on P-SPICE Platform.
