Microchip Technology, Inc. 400V FREDFET FREDFET-400V

Power MOS V® can still provide the best trade-off between performance and cost in some applications. Power MOS V® utilizes a low resistance aluminum metal gate structure. This allows for faster gate signal propagation than is possible with conventional polysilicon gate structures. The result is extremely low internal chip equivalent gate resistances (EGR) that are up to an order of magnitude lower than competitive devices which enables uniform high speed switching across the entire chip. Body Diode Options MOSFETs and FREDFETs are available in all voltage ratings. A FREDFET is a MOSFET with a faster recovery intrinsic body diode. This results in improved reliability in ZVS circuits due to shorter minority carrier lifetime and increased commutation dv/dt ruggedness. If a fast recovery body diode is not needed, MOSFET versions are available.
