Abstract:
This paper analyzes the efficiency of silicon MOSFETs in SMD packages with top-side cooling compared to bottom-side cooling packages in terms of thermal performance, lowering both thermal resistance and operating temperatures. It will show how reducing the junction temperature helps to boost power efficiency due to a smoother variation of the main silicon MOSFET parameters due to temperature changes such as RDS(on) and Vth level as well as reduces total conduction and switching losses.
