These pads are placed between a TO-220 component (MOSFET, transistor, voltage regulator) and a metal heatsink to provide \u003cstrong\u003ethermal conductivity while maintaining electrical insulation\u003c\/strong\u003e. Without insulation, the metal tab of a TO-220 package is electrically connected to one of its pins — mounting directly to a grounded heatsink would cause a short circuit.
