Application Scenarios & Design Considerations

P-Channel 1.8-V (G-S) MOSFET

Alternative Part Number

  • DMP3098L-7 --: P-channel MOSFET in SO-8 with comparable RDS(on) and voltage rating, suitable drop-in replacement for load switching applications.
  • FDS4935A --: P-channel MOSFET in SO-8 with similar current and voltage ratings, widely available and electrically compatible.
  • AO3401A --: P-channel MOSFET with comparable voltage rating and low RDS(on), though smaller package; usable where board space allows and current requirements are moderate.
  • AO4407A --: P-channel MOSFET in SO-8 with 30V rating and low RDS(on), a common alternative for power management circuits.
