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.
