EL SEGUNDO, Calif. — International Rectifier, IR® (NYSE: IRF), a world leader in power management technology, today announced the introduction of the IRFH7185TRPbF 100V FastIRFET™ power MOSFET that delivers benchmark performance for DC-DC power supplies used in telecom applications.

The IRFH7185TRPbF utilizes IR’s new 100V FastIRFET™ process to offer benchmark Rds(on)*Qg figure of merit to deliver higher efficiency and increased power density as well as enhanced system reliability.

“The IRFH7185TRPbF offers ultra-low Rds(on) with significantly lower gate charge than alternative devices to enable high performance from light load to full load. The new 100V FastIRFET™ device structure offers a twenty percent (20%) improvement in avalanche current density to deliver the industry’s most robust solution for DC-DC telecom power supplies,” said David Schroeder, Executive Director, IR’s Power Management Devices Business Unit.

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 IRFH7185TRPbF is qualified to industrial grade and moisture sensitivity level 1 (MSL1), and is available in an industry standard 5x6 PQFN package that features an environmentally friendly, lead-free and RoHS compliant bill of materials.
