International Rectifier family of motor vehicle qualified MOSFETs

International Rectifier has introduced its first dedicated family of motor vehicle qualified MOSFETs for a range of applications requiring low on-state resistance including electric power steering, integrated starter alternator pump and motor control, DC-DC conversion, battery switch, and other heavy loads on internal combustion engine and hybrid vehicle platforms.

The devices, built on Gen 10.2 technology, deliver on-state resistance as low as 1.0 mΩ RDS(on) (maximum) and are available across a range of voltages from 24 to 100 in a variety of surface mount device and through-hole packages. Several of the devices feature revised maximum current ratings of up to 240 A in a D2Pak-7P and 195 A in a D2Pak.

The MOSFETs are subject to dynamic and static part average testing combined with 100% automated wafer level visual inspection as part of the company’s quality initiative targeting zero defects. AEC-Q101 qualification requires that there is no more than a 20% change in RDS(on) after 1000 temperature cycles of testing. However, in extended testing, IR’s AU Bill of Materials demonstrated a maximum RDS(on) shift of less than 10% at 5000 temperature cycles.

The devices are qualified according to AEC-Q101 standards and feature an environmentally friendly, lead-free and RoHS-compliant bill of materials.
