Application Scenarios & Design Considerations

SURFACE MOUNT GLASS PASSIVATED ZENER

Alternative Part Number

  • 1N5359B --: Same 24V 5W zener diode rating in a DO-201 package, widely available and a common drop-in replacement for the SML4756.
  • BZX85C24 --: 24V 1.3W zener from Vishay with similar voltage tolerance; suitable when lower power dissipation is acceptable and keeps the same manufacturer.
  • 1N4749A --: 24V 1W zener diode in DO-41 package, a standard alternative for lower-power applications requiring the same zener voltage.
