The 7106DG is a Heat Sink made of copper with tin plated finish. This PCB surface mount heat sink features horizontal mounting orientation. This non-electronic component is functionally unaffected by the normal soldering or reflow processes used for semiconductor circuits. The heat resistance time or heat resistance temperature is not applicable for the component. This surface mount heat sink is suitable for use with D2 Pak (TO-263) power SO-10 (MO-184) package semiconductors.
