INTERNATIONAL Rectifier has released 75V and 100V Hexfet synchronous rectification MOSFETs. They can provide efficiency and power density improvements when used to replace traditional Schottky rectification MOSFETs.
The IRFB4310 has an RDS(on) of 7mΩ at 100V while the IRFB3207 has an RDS(on) of 4.5mΩ at 75V. Both have good body diode performance and are designed for ac-dc synchronous rectification for server, desktop and laptop adaptors.
They are also suitable for dc-dc, low voltage motor drive and automotive applications.
