STB40NF20:N-channel 200V - 0.038Ohm -40A- D2PAK/TO-220/TO-220FP/TO-247

This Power MOSFET series realized with STMicroelectronics unique STripFET process has specifically been designed to minimize input capacitance and gate charge. It is therefore suitable as primary switch in advanced high-efficiency isolated DC-DC converters.

Key Features

  • Gate charge minimized
  • Very good manufacturing repeatability
  • Very low intrinsic capacitances
  • 100% avalanche tested
  • Excellent figure of merit (RDS *Qg )
