In summary, heat sinks are an important element in thermal management as evidenced throughout this product training module. Without a heat sink, the silicon junction inside a transistor package can easily exceed its operating limits. By determining the various parameters of the application such as ambient temperature, power dissipation, thermal impedance paths, and more, one can better select the proper heat sink for the job. Once the thermal requirements are determined, Same Sky is here to help with a range of stamped and extruded heat sink options.
