International Rectifier – 75V StrongIRFET™ Power MOSFET Family

IR_November2014_pg26IR-logo
The new expansion of IR’s StrongIRFET MOSFET portfolio includes 75V devices for a wide variety of industrial applications including power tools, light electric vehicle (LEV) inverters, DC motor drives, Li-Ion battery pack protection, hot-swap and switched mode power supply (SMPS) secondary-side synchronous rectification.

The new family of 75V StrongIRFET power MOSFETs feature ultra low on-state resistance (RDS(ON)) for improved performance in low frequency applications, very high current carrying capability, soft body diode, and 3V typical threshold voltage to improve noise immunity. The surface mount packages are headlined by the IRFS7730-7P device in a rugged 7-pin D2-Pak offering an RDS(ON) max of only 2mΩ and a peak current of 240A. Each device in the family is 100% avalanche tested at industry highest avalanche current levels to ensure the most robust solution for demanding industrial applications. The devices are available in surface mount and thru-hole packages.
