Board Level Heat Sinks BOARD LEVEL POWER SEMICONDUCTOR HEAT SINKS 217 SERIES 2 Surface Mount Heat Sinks D PAK, TO-220, SOT-223, SOL-20 Compatible with surface mount technology (SMT) automated production techniques for ease of assembly and a variety of soldering methods, these heat sinks allow greater packaging densities and reduction in PC-board area, increasing the power dissipation of surface mount devices (SMDs) while maintaining and improving manufacturers' component thermal specifications. FEATURES AND BENEFITS: • No interface material is needed • Copper with tin-lead plating for improved solderability and assembly • Both the component and the heat sink are installed on the PC-board utilizing standard SMT assembly equipment for ”Tape & Reel” and “Tube” formats • EIA standards and ESD protection are specified • Can be used with water soluble or no clean SMT solder creams or other pastes Height Above Footprint Thermal Performance at Typical Load Standard PC Board Dimensions Package Package Natural Forced P/N in.
