International Rectifier Introduces Higher-Efficiency MOSFETs for Emerging Automotive Applications
EL SEGUNDO, Calif.--Sept. 6, 2002--International Rectifier, IR(r) , introduces an expanded and improved portfolio of automotive HEXFET(r) power MOSFETs with 10% lower on-resistance than previous devices. The new series includes the IRFR3504 and IRFU3504, featuring 9.2 milliohms on-resistance, and are among the best-performing, lowest on-resistance, Q101-qualified D-Pak and I-Pak automotive MOSFETs on the market.Typical applications include emerging 42V and current 14V automotive sub-systems such as cooling fan controls, integrated starter alternator (ISAD) circuits, synchronous rectifier alternators, electrical power steering (EPS), fuel injectors, solenoid and relay drivers, air bag systems, anti-lock brake systems and window and door lifts.
The lower on-resistance rating of the new MOSFETs increases efficiency and reduces power loss and thermal resistance. The new MOSFETs are rated for repetitive avalanche up to 175 degrees Celsius. The TO-220 and D-Pak devices are Q101-qualified to 175 degrees Celsius and are fully characterized avalanche energy rated for automotive applications. The D2Pak and TO-262 package devices are industrial-qualified.
"Low on-resistance leads to a reduction in the number of parallel devices, shrinking circuit footprint and offering similar performance to larger outline devices. This `smaller yet similar' efficiency increase is a main ingredient in the quest for improved automotive efficiency and better miles-per-gallon," said Randy Frank, Manager, North American Automotive Marketing at International Rectifier.
