Application Scenarios & Design Considerations

Surface Mount Zener Diodes

Alternative Part Number

  • 1N4747A --: Same 20V 1W zener diode in the classic 1N47xx axial series; widely available and electrically equivalent to the SML4747A.
  • BZX85C20 --: 20V 1.3W zener in DO-41 package from the same manufacturer; higher power rating provides margin and is a common cross for 1W zeners.
  • 1N5357B --: 20V 5W zener diode in DO-201 package; suitable when higher power dissipation is acceptable and offers a robust alternative.
