International Rectifier has introduced the 25V FastIRFET family of innovative power MOSFETs for DC-DC synchronous buck applications including advanced telecom and netcom equipment, servers, graphic cards, desktop, ultrabook and notebook computers. The FastIRFET family features IR’s latest generation silicon in an industry standard PQFN package that delivers benchmark power density for discrete DC-DC converters.

The family includes the IRFH4201 that offers on-state resistance (RDS(on)) as low as 0.7 milliOhms, and the IRFH4210D and IRFH4213D monolithic FETKY devices designed to reduce ringing and further improve system efficiency.

The advanced 25V FastIRFET MOSFETs offer industry leading power density for discrete high performance DC-DC switching applications. The devices complement IR’s integrated SupIRbuck, PowIRstageand power block platforms to offer designers a broad array of high performance DC-DC options.

Optimized for 5V gate drive applications, IR’s FastIRFET devices work with any controller or driver to offer design flexibility while delivering higher current, efficiency and frequency capability in a small footprint. The devices are available in industry standard 5x6 and 3.3x3.3mm PQFN packages that feature an environmentally friendly, lead-free and RoHS compliant bill of materials.
