IR Expands Its Family of Automotive-Qualified MOSFETs Featuring Low On-State Resistance

Jul 29, 2010 | Technology Media

EL SEGUNDO, Calif. — International Rectifier, IR® (NYSE: IRF), a world leader in power management technology, today announced the expansion of its dedicated family of automotive qualified power MOSFETs for applications requiring low on-state resistance (RDS(on)) including on-board power supplies and heavy loads on Internal Combustion Engine (ICE) platforms, micro and full hybrid platforms

Delivering RDS(on) as low as 2.6 mOhm at 55 V, the family of devices ranges from 40 V to 100 V and includes the first 75 V offerings. With higher voltages well suited for use in 24 V truck systems, several of the devices feature the new revised maximum current ratings of up to 240 A in a D2Pak-7P and 195 A in a D2Pak.

"With the assurance of IR's heritage in MOSFET technology and robust manufacturing, testing and qualification processes, the expansion of our family of dedicated devices offers customers an even wider choice of voltages and packages for their automotive design," said Benjamin Jackson, product manager, IR's Automotive Products Business Unit.

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. However, in extended testing, IR's new AU Bill of Materials demonstrated a maximum RDS(on) shift of less than 10 percent at 5,000 temperature cycles, showing the strength and ruggedness of the Bill of Materials.

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