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