Application Scenarios & Design Considerations

30V Single N-Channel HEXFET Power MOSFET in a D-Pak package

Alternative Part Number

  • FDD8870 --: N-channel logic-level MOSFET in DPAK with comparable 30V/60A ratings and low RDS(on), a direct drop-in replacement for the IRLR3103TR.
  • SUD50N03-10 --: 30V N-channel MOSFET in DPAK with similar current capability and low on-resistance, suitable for switching applications replacing the IRLR3103TR.
  • BUK9215-55A --: Logic-level N-channel MOSFET in DPAK with comparable voltage and current ratings, offering a functional alternative for the IRLR3103TR.
  • IRF3708PBF --: N-channel MOSFET with comparable 30V class and low on-resistance, widely available and a common substitute for logic-level switching applications.
  • FDP8870 --: 30V N-channel MOSFET with low RDS(on) in TO-220, suitable replacement for power switching where the original DPAK part is used.
  • STP55NF06 --: Popular 60V N-channel MOSFET with higher voltage margin and robust current rating, usable as a conservative drop-in in many switching circuits.
