IR Introduces HEXFET Automotive Power MOSFETs
International Rectifier Corp. (IR, El Segundo, CA) introduced an expanded and improved portfolio of automotive HEXFET® power MOSFETs with 10 percent lower on-resistance than previous devices. The new series includes the Q101-qualified D-Pak and I-Pak IRFR3504 and IRFU3504 automotive MOSFETs, featuring 9.2 milliohms on-resistance.
Typical applications include emerging 42V and current 14V automotive sub-systems such as cooling fan controls, integrated starter alternator circuits, synchronous rectifier alternators, electrical power steering, 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 C. The TO-220 and D-Pak devices are Q101-qualified to 175 degrees C 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.
Pricing begins at $0.849 each in 10,000-unit quantities for the IRFR3405. Samples are available now.
