Application Scenarios & Design Considerations

P-Channel 1.8V Specified PowerTrench MOSFET

Alternative Part Number

  • FDS6690A --: N-channel MOSFET in SO-8 with comparable RDS(on) and voltage rating, widely available and pin-compatible for most switching applications.
  • IRF7413 --: Similar N-channel logic-level MOSFET in SO-8 package with matching current and voltage ratings, suitable drop-in replacement.
  • AO4406 --: N-channel MOSFET in SO-8 with comparable on-resistance and gate charge, good alternative when supply of the original is limited.
