Application Scenarios & Design Considerations

150V Single N-Channel HEXFET Power MOSFET in a SO-8 package

Alternative Part Number

  • SI4459ADY-T1-GE3 --: P-channel MOSFET in SO-8 with comparable voltage and on-resistance ratings, widely available and pin-compatible for many IRF7451 applications.
  • FDS4935A --: Dual P-channel MOSFET in SO-8 offering similar RDS(on) and current handling, suitable as a functional substitute in load-switch circuits.
  • NTMS4407NR2G --: P-channel MOSFET in SO-8 with 30V rating and low on-resistance, a practical drop-in alternative when layout and gate drive match.
  • DMP3010LK3Q-13 --: P-channel MOSFET in a similar power package with matching voltage class and low on-resistance, usable as an alternative with layout verification.
