Application Scenarios & Design Considerations

Leaded 40V Single N-Channel HEXFET Power MOSFET in a SO-8 package

Alternative Part Number

  • SI4840BDY-T1-E3 --: N-channel MOSFET in SO-8 with comparable RDS(on) and voltage rating, widely available and a common drop-in for IRF7842 applications.
  • FDS8880 --: N-channel logic-level MOSFET in SO-8 with similar current and RDS(on) characteristics, suitable as a functional replacement.
  • CSD17501Q5A --: NexFET power MOSFET with low RDS(on) and comparable ratings, usable as an alternative where layout allows a different package footprint.
