Eppes, Milanovic, and Quarshie Publish Research Paper
The paper discusses the heat transfer process in a TO-220 transistor package and the benefits of certain design features. Power transistors require heat sinks to dissipate thermal energy and keep junction temperatures below the recommended limit. A significant increase in useful life can be achieved by a small reduction in operating temperature. Parametric studies of heat sink size, emissivity and convective cooling coefficient impact on the steady-state temperature of the assembly were reported. This work was initiated and done in part during the new course ES 591 – Multiphysics Modeling.
