International Rectifier IRF634S HEXFET Power MOSFET PD-9.1005 Surface Mount Available in Tape & Reel D _ Dynamic dv/dt Rating Vpss = 250V Repetitive Avalanche Rated Fast Switching Rpsvon) = 0.450 . G Ease of Paralleling Simple Drive Requirements $ Ip =8.1A Description Third Generation HEXFETs from International Rectifier provide the designer with the best combination of fast switching, ruggedized device design, low on-resistance and cost-effectiveness. The SMD-220 is a surface mount power package capable of accommodating die sizes up to HEX-4. It provides the highest power capability and the lowest possible on-resistance in any existing surface mount package. The SMD-220 is suitable for high current applications because of its low internal connection resistance and can dissipate up to 2.0W in a typical surface mount application.
