Abstract :
Discrete high power packages: TO-220FP, TO-247, TO-3P are investigated for their thermal-mechanical behaviors. Junction-to-ambient thermal resistance measurements and Computational Fluid Dynamics (CFD) simulations are utilized to judge the thermal performance of these packages with the same material properties. The finite element method (FEM) simulations of temperature cycling is also applied to analyze the internal stress and strain, impact of different die size and thickness have been compared, which provides references for further studies and power packages optimization.
