The IXFH40N50Q is an N-channel enhancement mode Power MOSFET designed for high-power switching applications, featuring a drain-source voltage rating of 500 V and a continuous drain current of 40 A at 25°C. It comes in a TO-247 AD package, weighing 6 g, with a thermal resistance from junction to case of 0.25 K/W. The device has a typical on-resistance of 0.14 Ω at 10 V gate voltage and a gate charge of 26 nC, enabling fast switching with low drive losses. It is avalanche-rated for unclamped inductive load switching, with an energy rating of 50 mJ, and meets the UL 94 V-0 flammability standard. The part operates from -55°C to 150°C and is rated for a maximum junction temperature of 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
