Application Scenarios & Design Considerations

100V N-Channel A-FET

Alternative Part Number

  • STP60NF06 --: N-channel MOSFET in TO-220 with comparable voltage and current ratings, widely available and a common drop-in substitute for the IRFW520A.
  • IRFZ44N --: Popular logic-level N-channel MOSFET in TO-220 with similar RDS(on) and current capability, frequently used as a replacement in switching applications.
  • FQP50N06 --: 60V N-channel MOSFET in TO-220 with comparable current rating and low on-resistance, suitable alternative when the original is unavailable.
  • STP5NK50ZFP --: 500V N-channel MOSFET in TO-220FP package with comparable RDS(on) and current rating, suitable drop-in replacement for switching applications.
  • FQP5N50C --: 500V N-channel MOSFET with similar voltage and current ratings, widely available and commonly used as an alternative in power supplies.
  • IRF520NPBF --: 100V logic-level N-channel MOSFET in TO-220, lower voltage but often acceptable in low-voltage switching circuits where the original is overrated.
