Application Scenarios & Design Considerations

N-CHANNEL 20V

Alternative Part Number

  • IRLZ44N --: Logic-level N-channel MOSFET with comparable 55V/47A rating and low RDS(on), widely used as a drop-in for 40NF02L-class parts in low-voltage switching.
  • FQP30N06L --: Logic-level 60V/32A N-channel MOSFET with similar gate drive requirements and low on-resistance, suitable replacement for low-side switching applications.
  • IRFZ44N --: Standard 55V/49A N-channel MOSFET with similar current capability; note it is not logic-level, so verify gate drive voltage before substituting.
