MOSFETs boost power supply density
New high efficiency power MOSFETs enable a parts count reduction of 30% or more in secondary synchronous rectification, full-bridge topology power supplies compared with competing devices.
International Rectifier has introduced very high efficiency 75 and 100V HEXFET power MOSFETs in the TO-220 package that enable a parts count reduction of 30% or more in secondary synchronous rectification, full-bridge topology power supplies compared with competing devices in the same package The new 75V MOSFETs are designed to shrink circuit size and increase power density in high power server AC/DC switch-mode power supplies (SMPS) with 12V output or in 48V rail ORing circuits

International Rectifier has introduced the world's first 1000V radiation-hardened power MOSFET.
The new 100V devices suit high power flyback secondary rectification or offer enhanced primary-side efficiency in high power telecom isolated 48V DC/DC convertors.
In addition, the new MOSFETs can be used in stepper motor and brushless DC motor drive applications.
The IRFB3077PbF is a 75V MOSFET with 3.3mohm maximum device on-resistance, and enables a 30% parts count reduction (from ten TO-220 devices to seven TO-220 devices), with a reduced PCB area and heatsinking for higher power density in 3kW server SMPS with 12V output.
The IRFB4110PbF is a 100V MOSFET with 4.0mohm maximum device on-resistance, and can slash component count in half, reducing PCB area and reducing heatsink size.
The new synchronous HEXFET MOSFETs are available now and are lead-free and RoHS-compliant.
