International Rectifier (IR) has expanded its offering of 40 V to 100 V automotive qualified MOSFETs including a family of logic level devices. According to IR, the MOSFETs are built on its AU Gen 10.2 trench technology and are suitable for heavy load applications used in traditional Internal Combustion Engine (ICE) platforms and micro and hybrid vehicle platforms.
The MOSFETs are optimized to deliver low on-state resistance (RDSon) across a range of voltages from as low as 8 mOhms at 55V. Additionally, the logic level MOSFET devices simplify gate drive requirements while saving board space and component count.
All of the devices are qualified according to AEC-Q101 standards. 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, according to IR in extended testing its new AU Bill Of Materials exhibited a maximum RDS(on) shift of only 12% at 5,000 temperature cycles.
Pricing ranges from US $0.20 each for the AUIRFR120Z in 100,000-unit quantities to US $0.89 each in 100,000-unit quantities for the AUIRL1404ZS.
