Product Description

The unique design (Patent Pending) combines tin plated, solderable rods with an aluminum extruded heat sink body. These rods (or rollers) are mated mechanically to the heat sink by forging to reduce the thermal resistance between the heat sink body and the solderable feet. Specifically designed for use with the increasingly popular TO-252, TO-263 and TO-268 packages, the D Series affords the user superior thermal performance over the more common stamped aluminum heat sinks. By eliminating the staking joint typically used in stamped heat sinks, the resulting air gap and thermal bottleneck is also eliminated, while surface area for cooling is maximized with the extruded fins of the D Series body.

Features
  • Increased thermal performance up to 30% over bright copper heat sinks from improved radiation of the black finish
  • Increased surface areas by 3 times therefore thermal performance up to 300% over the aluminum stamped heat sinks on markets
  • Unique aluminum extrusion design reduces the heat sink cost versus similar designs utilizing copper
  • Light weight aluminum construction allows faster pick and place assembly reducing the manufacturing cycle time
  • Radius mounted Rollers are designed for maximizing heat transfer from the component and avoiding the thermal bottleneck seen in stamped and staked heat sinks
