High-current MOSFETs in D2Pak

9 February 2005 Power Electronics / Power Management

International Rectifier has introduced a pair of 55 V rated Q101-qualified automotive HEXFET power MOSFETs rated for continuous duty in the D2Pak outline. The 55V devices are designed to increase safety margin in specific circuitry and load topologies where the higher voltage rating would handle load-dump transients on the battery line, or transients caused by loads with strong inductive nature. The IRF3805S-7P (160 A continuous) and IRF1405ZS-7P (120 A continuous) are designed for heavy-duty, high-current automotive applications such as electronic power steering, 14 V integrated starter alternator systems and advanced alternator active rectification.
