R-C Thermal Model Parameters
DESCRIPTION
The parametric values in the R-C thermal model have been
derived using curve-fitting techniques. R-C values for the
electrical circuit in the Foster/tank and Cauer/filter
configurations are included. When implemented in P-SPICE,
these values have matching characteristic curves to the
single-pulse transient thermal impedance curves for the
MOSFET.
These RC values can be used in the P-SPICE simulation to
evaluate the thermal behavior of the MOSFET junction
temperature under a defined power profile. These
techniques are described in application note AN609,
“Thermal Simulation of Power MOSFETs on the P-SPICE
Platform”.
