The IXFR44N50Q is an N-channel enhancement mode power MOSFET rated for 500 V drain-source voltage and 34 A continuous drain current at 25°C, designed for hard switching and resonant-mode applications including DC-DC converters, battery chargers, and AC motor control. It features an ISOPLUS247TM package with an electrically isolated backside, providing 2500 V rms isolation and a low drain-to-tab capacitance of less than 30 pF. The RDS(on) is 120 mΩ at 25°C, with a thermal resistance junction-to-case of 0.40 K/W. The device is avalanche-rated, supports unclamped inductive load switching, and has a fast intrinsic diode with a reverse recovery time of 250 ns. Operating junction temperature ranges from -55°C to 150°C.
The Q-Class series devices are popular Power MOSFETs (HiPerFET™) for both hard switching and resonant mode applications, offering low gate charge and excellent ruggedness with a fast intrinsic diode. They are available in many standard industrial packages including isolated types.Advantages: Easy assembly High Power density Space savings International standard packages Rugged polysilicon gate cell structure Rated for Unclamped Inductive Load Switching (UIS) Fast intrinsic Rectifier
