Application Scenarios & Design Considerations

55V Single N-Channel HEXFET Power MOSFET in a D2-Pak package

Alternative Part Number

  • STP55NF06 --: N-channel 60V MOSFET in TO-220 with comparable RDS(on) and current rating, widely available and a common drop-in for IRFZ44N-type parts.
  • FQP30N06L --: 60V logic-level N-channel MOSFET in TO-220 with similar current capability and low RDS(on), suitable replacement in most switching applications.
  • AOD4184 --: 40V N-channel MOSFET with low RDS(on) and good current handling; acceptable alternative where the lower voltage rating is within design margin.
