Application Scenarios & Design Considerations

P-CHANNEL POWER MOSFET

Alternative Part Number

  • FQP9N20 --: Same 200V N-channel MOSFET class in a TO-220 package from the same manufacturer family, widely available and a common substitute for SFP9520.
  • IRF620 --: 200V N-channel MOSFET with comparable current and RDS(on) ratings, pin-compatible TO-220 device from a different series and vendor.
  • STP10NK20 --: 200V N-channel MOSFET offering similar voltage and current capability, suitable drop-in alternative from a different manufacturer and series.
  • IRF9540N --: P-channel MOSFET with similar -100V/-19A ratings, widely available and a common substitute for the SFP9520 in switching applications.
  • FQP47P06 --: P-channel MOSFET from the same manufacturer family with comparable voltage/current capability, suitable for power switching replacements.
  • IRF4905 --: P-channel MOSFET rated -55V/-74A with low RDS(on), a robust alternative when higher current margin is acceptable.
