The unique design (Patent Pending) combines tin plated, solderable rods with an alu- minum extruded heat sink body. These rods (or "roll- ers") are mated mechanically to the heatsink by forging to reduce the thermal resistance between the heatsink 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 heatsinks. By eliminating the staking joint typically used in stamped heatsinks, the result- ing air gap and thermal “bottle- neck” is also eliminated, while surface area for cooling is maximized with the extruded fins of the D Series body.
