Use Fourier’s law to examine the thermal path from a TO-220 power device through a silicone cap to a heatsink, with insulation and package-fit checkpoints.
TO-220 packaged power components need both thermal management and electrical insulation. This article explains how a one-piece heat conductive silicone cap addresses both, and what to check when selecting a size.
