International Rectifier automotive power MOSFETs

The AUIRFR4292 and AUIRFS6535 are automotive-qualified power MOSFETs featuring low on-state resistance for Piezo injection systems for both gasoline and diesel engines.

The 250 V AUIRFR4292 offers a maximum Rds(on) of 345 mOhm in a DPAK package, and the 300 V AUIRFS6535 features a maximum Rds(on) of 185 mOhm in a standard D2PAK package.

This makes the MOSFETs suited for Piezo injection applications where high-voltage is required to drive the actuators, and is claimed to ensure faster response and more precise control than magnetic solenoid injection systems.

As part of IR’s automotive quality initiative targeting zero defects, the MOSFETs are subject to dynamic and static part average testing combined with 100% automated wafer level visual inspection.

Whilst AEC-Q101 qualification requires that there is no more than a 20% change in Rds(on) after 1000 temperature cycles, extended testing of the MOSFETs demonstrated a maximum Rds(on) shift of less than 10% at 5000 temperature cycles. They are also feature an environmentally-friendly, lead-free and RoHS compliant bill of materials.
