Board Level Heat Sinks BOARD LEVEL POWER SEMICONDUCTOR HEAT SINKS 217 SERIES Surface Mount Heat Sinks D 2PAK, 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 Standard P/N Height Above PC Board in.
