Application Scenarios & Design Considerations

400V N-Channel MOSFET

Alternative Part Number

  • STP60NF06 --: N-channel 60V power MOSFET in TO-220 with comparable RDS(on) and current rating, widely available and pin-compatible for most switching applications.
  • FQP50N06 --: 60V N-channel MOSFET in TO-220 offering similar voltage and current capability, a common drop-in substitute for general power switching.
  • IRFZ44N --: Popular 55V N-channel MOSFET in TO-220 with low RDS(on), close enough ratings to serve as a functional replacement in many circuits.
