Reigate, UK A new and expanded range of 60 V and 75 V HEXFET MOSFETs from International Rectifier can be used in DC-DC converters and low-voltage motor drives and for AC-DC synchronous rectification in servers, laptop adaptors, and desktop power supplies.
In the ongoing effort to increase the power density and speed of data processing circuits, the power supply requirement for higher density is increasing. The new IRFB/S/SL3206, 3306, 3207Z and 3307Z families of MOSFETs offer superior synchronous rectification performance through improved RDS(on) in AC-DC SMPS applications, and also improve power density by lowering RDS(on) up to 10 percent compared to the previous industry standards.
4.1 mohm to 5.8 mohm, and for the 60 V devices, from 3.0 mohm to 4.2 mohm. The new devices are available in TO-220, D2Pak and TO-262 qualified to industrial grade and moisture sensitivity level 1 (MSL1). IR’s selection of packages enables a simplified performance upgrade path for existing designs. All package types are lead-free and designed to help customers meet the Restriction of Hazardous Substances in Electrical and Electronic Equipment (RoHS) directive in the newest SMPS solutions without any compromise in performance.
The new 75 V synchronous MOSFETs, when used with the SmartRectifier IR1167 IC, also have online design software available at IR’s myPower site. Designers enter application conditions and performance requirements to obtain recommended IC and MOSFET chip sets which can be sorted by performance and system cost.
