IR Introduces Automotive Power MOSFETs Optimized for Piezo Injection Systems for Gasoline and Diesel Engines

EL SEGUNDO, Calif. International Rectifier, IR (NYSE: IRF), a world leader in power management technology, today announced the introduction of the AUIRFR4292 and AUIRFS6535 automotive-qualified power MOSFETs featuring low on-state resistance (Rds(on)) for Piezo injection systems for both gasoline and diesel engines.

Utilizing IRs latest generation of proven automotive power MOSFET technology, the AUIRFR4292 and AUIRFS6535 extend the range of IRs automotive-qualified MOSFET portfolio to breakdown voltage up to 300V. The 250V AUIRFR4292 offers a maximum Rds(on) of 345mOhm in a DPAK package, and the 300V AUIRFS6535 features a maximum Rds(on) of 185mOhm in a standard D2PAK package.

Offering low Rds(on) in standard surface mount packages, these new 250V and 300V power MOSFETs are well suited for Piezo injection applications where high-voltage is required to drive the actuators and ensure faster response and more precise control than magnetic solenoid injection systems, said Jifeng Qin, Product Manager, Automotive MOSFETs, IRs Automotive Products Business Unit.

IRs automotive MOSFETs are subject to dynamic and static part average testing combined with 100 percent automated wafer level visual inspection as part of IRs 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 IRs new AU bill of materials demonstrated a maximum Rds(on) shift of less than 10% 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, feature an environmentally friendly, lead-free and RoHS compliant bill of materials.
