Advanced Process Technology Ultra Low On-Resistance l Dynamic dv/dt Rating l 175°C Operating Temperature l Fast Switching l Fully Avalanche Rated l Lead-Free Description l l IRF2807SPbF IRF2807LPbF D PD - 95945 HEXFET® Power MOSFET VDSS = 75V RDS(on) = 13mΩ S G The D2Pak 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 D2Pak 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. The through-hole version (IRF2807L) is available for lowprofile applications. Advanced HEXFET® Power MOSFETs from Internationa [ ... ]
