IR introduces new automotive power MOSFET for engines

International Rectifier has released its latest batch of automotive-qualified power MOSFETs geared toward Piezo injection systems for both gasoline and diesel engines. The AUIRFR4292 and AUIRFS6535 features low on-state resistance (Rds(on)) and extends range of IR's MOSFET line 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.

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. AEC-Q101 qualification requires that there is no more than a 20 per cent 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.

The new devices pass the AEC-Q101 standards with its environment-friendly, lead-free and RoHS compliant bill of materials, according to the company release.
