IR Introduces Family of Rugged Automotive Qualified Planar MOSFETs

Jan 26, 2011 | Market News

EL SEGUNDO, Calif. — International Rectifier, IR® (NYSE: IRF), a world leader in power management technology, today 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 utilizing IR's proven planar technology includes 55V and 150V standard gate drive N Channel MOSFETs, and -55V and -100V standard gate drive P channel MOSFETs suitable for high-side switch applications and require no additional charge pump for gate drive. The 30V, 55V and 100V 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 optimized for low on-state resistance (Rds(on)).

"By utilizing IR's proven planar technology, these new automotive dedicated devices perform well in the linear mode and in applications where a rugged MOSFET is needed to drive highly inductive loads. Moreover, the devices are well suited to vehicles using a higher board-net voltage such as trucks, said Benjamin Jackson, product manager, IR's Automotive Products Business Unit.

The 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 percent 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 percent change in RDS(on) after 1,000 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 5,000 temperature cycles, demonstrating the strength and ruggedness of the Bill of Materials.

Datasheets and qualification standards are available via the part number links found above. Spice models are available on request.
