Application Scenarios & Design Considerations

N-Channel Power Mosfets

Alternative Part Number

  • STP7N90K5 --: 900V N-channel MOSFET with similar 7A current rating and comparable RDS(on), suitable drop-in replacement for switching applications.
  • IRFBE30 --: 800V N-channel MOSFET rated around 4.8A, close voltage class and package, usable in lower-current 900V designs with margin check.
  • IXTP8N90P --: 900V N-channel MOSFET with 8A rating, matches voltage and current class closely for high-voltage switching circuits.
  • IRFBF30 --: 900V N-channel MOSFET with comparable voltage and current capability, widely available and commonly used as an alternative in power supplies.
  • 2SK3569 --: 900V N-channel MOSFET with similar ratings and package, a practical substitute for high-voltage switching circuits.
  • FQP7N90C --: 900V 7A N-channel MOSFET in TO-220 package with similar voltage and current ratings, widely available alternative.
