International Rectifier has introduced a family of automotive-qualified planar MOSFETs for a variety of applications used in internal combustion engine (ICE), hybrid and full electric vehicle platforms.
The family of new devices, utilising IR’s proven planar technology, includes 55 V and 150 V standard gate drive N-channel MOSFETs, and -55 V and -100 V standard gate drive P-channel MOSFETs, suitable for high-side switch applications, requiring no additional charge pump for gate drive. The 30 V, 55 V and 100 V logic level gate drive N-channel MOSFETs simplify gate drive requirements and help reduce board space and component count. All of the new devices are optimised for low on-state resistance (Rds(on)).
The new devices are qualified according to AEC-Q101 standards, feature an environmentally friendly, lead-free and RoHS compliant bill of materials, and are part of IR’s automotive focused Zero Defect Initiative. All of IR’s automotive MOSFETs are subject to dynamic and static part average testing combined with 100% 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% change in Rds(on) after 1000 temperature cycles of testing. However, in extended testing IR’s new AU bill of materials exhibited a maximum Rds(on) shift of only 12% at 5000 temperature cycles.
