Application Scenarios & Design Considerations

1 Watt DL-41 Hermetically Sealed Glass Zener Voltage Regulators

Alternative Part Number

  • 1N4735A --: Same 6.2V 1W zener diode in the standard 1N47xx series; widely available and electrically equivalent to the ZM4735A.
  • BZX85C6V2 --: 6.2V 1.3W glass zener diode with similar voltage tolerance and DO-41 package, suitable drop-in replacement with slightly higher power rating.
  • 1N4735A-TR --: Alternative 6.2V 1W zener from a different manufacturer series, offering comparable specifications and good availability.
  • 1N4735ATR --: Direct 6.2V 1W DO-41 zener alternative from a different manufacturer, offering equivalent electrical characteristics for replacement use.
