N-channel 650 V, 0.056 Ohm typ., 42 A MDmesh M5 Power MOSFET in a TO247-4 package

This device is an N-channel MDmesh™ V Power MOSFET based on an innovative proprietary vertical process technology, which is combined with STMicroelectronics’ well-known PowerMESH™ horizontal layout structure. The resulting product has extremely low on-resistance, which is unmatched among silicon-based Power MOSFETs, making it especially suitable for applications which require superior power density and outstanding efficiency.

Key Features

  • Higher VDS rating
  • Higher dv/dt capability
  • Excellent switching performance thanks to the extra driving source pin
  • Easy to drive
  • 100% avalanche tested
