Using an Electro-Thermal Model for Vishay Siliconix Power MOSFETs on a PSpice Platform
Vishay Siliconix offers a combined electro-thermal PSpice model for power MOSFETs. The basic PSpice model is embedded with R-C thermal model parameters. One single electrical simulation, using a combined electro-thermal PSpice model, enables users to analyze the electrical as well as thermal behavior of Vishay Siliconix power MOSFETs in a design. This application note illustrates the step-by-step procedures for using an electro-thermal model on the PSpice platform. The example offers a complete walk-through, including the download, building an electrical schematic on OrCAD Capture, setting up and running the simulation, and obtaining electrical waveforms as well as thermal performance characteristics by selecting output parameters.
