This information is based on the manufacturer's datasheet.

Application Scenarios & Design Considerations

N-CHANNEL 400V

Alternative Part Number

  • IRF740 --: Industry-standard 400V N-channel MOSFET in TO-220, widely available and a common drop-in substitute for 400V/5A class devices.
  • FQP4N40 --: 400V N-channel MOSFET with similar voltage rating and current capability, suitable for switching applications as an alternative to the STP5NK40ZFP.
  • 2SK3569 --: 500V N-channel MOSFET offering higher voltage margin and comparable on-resistance, usable where a 400V part is specified.
