PD - 91016A IRFBC40S/L HEXFET® Power MOSFET Surface Mount (IRFBC40S) D Low-profile through-hole (IRFBC40L) VDSS = 600V Available in Tape & Reel (IRFBC40S) Dynamic dv/dt Rating RDS(on) = 1.2? 150°C Operating Temperature G Fast Switching ID = 6.2A Fully Avalanche Rated S 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 D2Pak is a surface mount power package capable ofthe accommodatingdie sizes up to HEX-4. It provides the highest power capability and the lowest possible on- resistance in any existing surface mount package. The D2Pak is suitable for high current applications because of its low internal connectio
