N-channel 950 V, 0.120 Ohm typ., 38 A MDmesh DK5 Power MOSFET in a TO-247 long leads package

These very high voltage N-channel Power MOSFETs are part of the MDmesh™ DK5 fast recovery diode series. The MDmesh™ DK5 combines very low recovery charge (Qrr) and recovery time (trr) with an excellent improvement in RDS(on) * area and one of the most effective switching behaviors, ideal for half bridge and full bridge converters.

Key Features

  • Fast-recovery body diode
  • Best RDS(on) x area
  • Low gate charge, input capacitance and resistance
  • 100% avalanche tested
  • Extremely high dv/dt ruggedness
