Compact power MOSFET delivers efficiency, high power density and cuts system costs

International Rectifier has introduced the automotive-qualified AUIRFN8403 COOLiRFET power MOSFET for automotive applications that require both compact size and high current performance including pump motor control and automotive body control.

Available in a compact PQFN 5x6mm package, the AUIRFN8403, the first in a family of new devices, uses IR’s advanced COOLiRFET 40V trench technology, delivering ultra-low 3.3mOhm on-state resistance (Rds(on)) and offering 95A high current carrying capability. The PQFN package features extended lead with end-lead plating to ensure effective solder-ability and an easy-to-inspect solder joint.

The AUIRFN8403 offers more than a 50% size reduction compared with conventional DPAK (TO-252) packages, and significant thermal performance improvement compared to an SO-8 package to provide a cost effective ultra-compact, high efficiency, high density solution for automotive applications

IR’s automotive MOSFETs are subject to dynamic and static part average testing combined with 100 percent automated wafer level visual inspection as part of IR’s automotive quality initiative targeting zero defects. AEC-Q101 qualification requires that there is no more than a 20 percent change in Rds (on) after 1,000 temperature cycles of testing.

The new device is qualified according to AEC-Q101 standards, features an environmentally friendly, lead-free and RoHS compliant bill of materials.
