Application Scenarios & Design Considerations

N-Channel 150-V (D-S) MOSFET

Alternative Part Number

  • FDS6680A --: N-channel MOSFET in SO-8 with comparable 30V/10A ratings and low RDS(on), a common drop-in replacement for the SI4848DY.
  • IRF7413ZPBF --: SO-8 N-channel MOSFET with similar voltage and current capability, widely available and electrically compatible in most switching applications.
  • AO4406A --: 30V N-channel MOSFET in SO-8 with low on-resistance, suitable as a functional substitute where exact Vishay matching is not required.
  • IRF7413Z --: Similar 30V N-channel MOSFET in SO-8 package with low on-resistance, suitable drop-in replacement.
