Application Scenarios & Design Considerations

400V Single N-Channel HEXFET Power MOSFET in a D-Pak package

Alternative Part Number

  • RFD3055LE --: N-channel logic-level MOSFET in TO-252 (DPAK) with comparable 60V/12A ratings, widely available and a common drop-in for IRFR320TR switching applications.
  • STD12NF06LT4 --: 60V N-channel MOSFET in DPAK with similar on-resistance and current capability, suitable replacement for low-side switching and power management circuits.
  • FDD6530A --: N-channel MOSFET in TO-252 with 30V/25A rating; usable in many IRFR320TR applications where lower voltage is acceptable, offering low RDS(on) and good thermal performance.
  • FQP9N40 --: 400V N-channel MOSFET in TO-220 with similar current and RDS(on) ratings, widely available and pin-compatible replacement.
  • STP9NK40Z --: 400V N-channel MOSFET with comparable voltage and current specs, suitable drop-in substitute for switching applications.
  • IRF740 --: 400V N-channel MOSFET with similar on-resistance and current capability, common industry-standard alternative.
