APT Expands Power MOS 7 Line with FREDFETs

Advanced Power Technology (APT, Bend, OR) expanded its recently introduced Power MOS 7 product line to include FREDFETs, resulting in fast, cool-running MOSFETs whose intrinsic diodes enable higher efficiency converters, according to the company.

Features include low gate charge and internal chip gate resistance for faster switching speeds and reduced switching losses, low RDS(on) for extremely low conduction losses, low thermal resistance and an increased power dissipation rating for higher current-handling capability, and a low intrinsic diode reverse-recovery charge for reduced losses and increased dv/dt ruggedness. Compared to the previous generations of APT’s FREDFETs, the Power MOS 7 FREDFETs offer up to 60 percent lower total gate charge, up to a 30-percent reduction in on-resistance, and increased current and power density.

Applications for the Power MOS 7 FREDFETs include half-bridge converters and full-bridge converters, or any other circuit in which the MOSFET’s intrinsic diode is called on to conduct. Power supply designers can now use the FREDFETs to improve the cost, power density and efficiency of their designs.

The new family of FREDFETs is available with voltage ratings from 100V through 1,000V. Packages include TO-247, D3, T-MAXTM, TO-264, the new 264 MAXTM and SOT-227. Samples are available now and production volume is planned for first-quarter 2002.
