Application Scenarios & Design Considerations

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

Alternative Part Number

  • FQP30N06L --: N-channel logic-level MOSFET in TO-220 with 60V/32A rating, close to IRFR1205's 55V/44A capability and widely available as a drop-in for many switching applications.
  • STP55NF06 --: 60V N-channel power MOSFET in TO-220 rated around 50A, matching the voltage class and current range of IRFR1205 for motor and power switching use.
  • IRLZ44N --: Logic-level 55V N-channel MOSFET in TO-220 with low RDS(on), same voltage rating as IRFR1205 and suitable for gate-drive circuits requiring logic-level threshold.
