Automotive MOSFETS suited for hybrid vehicles

International Rectifier (IR) announces a family of automotive-qualified MOSFETs delivering benchmark on-state resistance (Rds(on)) for applications such as electric power steering, integrated starter alternator pump and motor control, and other heavy loads on internal combustion engine and hybrid vehicle platforms.

The new family of trench HEXFET power MOSFETs is available across voltages from 40 to 200 V in a variety of surface mount device (SMD) packages. Benchmark Rds(on) as low as 1.25 mohm maximum at 40 V, 2.1 mohm maximum at 60 V, 2.6 mohm maximum at 75 V, and 4.0 mohm maximum at 100 V can be achieved. Some devices feature a maximum current rating to 240 A in a D2Pak-7P.

IR’s automotive MOSFETs are subject to dynamic and static part average testing combined with 100% automated wafer-level visual inspection. AEC-Q101 qualification requires that there is no more than a 20% change in Rds(on) after 1,000 temperature cycles of testing. In extended testing, the company's new AU bill of materials demonstrated a maximum Rds(on) shift of less than 10% at 5,000 temperature cycles.

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