MOSFETs claim benchmark low
on-resistance
A new range of 75 and 100V HEXFET MOSFETs is designed specifically for AC/DC synchronous rectification and ORing circuits.
International Rectifier has a new range of 75 and 100V HEXFET MOSFETs specifically for AC/DC synchronous rectification (SR) and ORing circuits The new MOSFETs feature benchmark low on-resistance - 7mohm for the 100V-rated IRFB4310, and 4.5mohm for the 75V-rated IRFB320 - to improve efficiency and power density in laptop/LCD adapter and server AC/DC SMPS applications

International Rectifier has introduced the world's first 1000V radiation-hardened power MOSFET.
MOSFETs improve 12V-input converter efficiency
Two new 20V HEXFET power MOSFET families from International Rectifier are designed to increase efficiency by up to 4% in 12V-input DC/DC convertors.
The new devices are suitable for the secondary side of many different AC/DC topologies including flyback, half-bridge, full-bridge and forward converters.
Historically, Schottky diodes were used as output rectification devices for high power density SMPS.
Significant efficiency improvement can be gained by replacing Schottky rectifiers with synchronous rectification MOSFETs.
Depending on application details, the new SR MOSFETs enable higher efficiencies and may allow a "two-for-one" exchange for competing devices to reduce component count, save PCB area and increase power density.
In addition, IR's selection of packages enables a simplified performance upgrade path for existing designs.
The new 75 and 100V devices are available in TO-220, D2Pak and TO-262 qualified to Q101 grade and moisture sensitivity level 1 (MSL1).
Lead-free packages are also available to help customers meet the RoHS Directive in the newest SMPS solutions without any compromise in performance.
The lead-free versions are the same price as standard parts.
