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.
R-C THERMAL MODEL FOR TANK CONFIGURATION
This document is intended as a SPICE modeling guideline and does not constitute a commercial product data sheet. Designers should refer to the appropriate data
sheet of the same number for guaranteed specification limits.
