IR Launches Family Of Low On-State Resistance MOSFETs For Automotive Apps

International Rectifier has introduced the company’s first dedicated family of automotive qualified MOSFETs for a range of applications requiring low on-state resistance (RDS(on)) including electric power steering (EPS), integrated starter-alternator (ISA) pump and motor control, DC-DC conversion, battery switch, and other heavy loads on internal combustion engine (ICE) and hybrid vehicle platforms.

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

IR’s automotive MOSFETs are subject to dynamic and static part average testing combined with 100% 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% change in RDS(on) after 1,000 temperature cycles of testing. In extended testing, IR’s new AU Bill of Materials demonstrated a maximum RDS(on) shift of less than 10% at 5,000 temperature cycles.
