• Low voltage regulation capability with specified tolerance series
• High thermal endurance supporting elevated junction temperatures

Applications

• Low voltage stabilizers

Procurement Notes

Verify the specific ordering code against the manufacturer's official documentation to ensure correct package type and tolerance class. Confirm that the component meets all required environmental and electrical specifications for the intended design application before finalizing procurement decisions.

Selection Notes

Select this component for circuits requiring precise low voltage regulation within the specified power dissipation limits. Ensure the operating environment remains within the defined thermal boundaries to maintain performance reliability and prevent exceeding absolute maximum ratings during operation.

Part Context

This part belongs to the 1N4728A to 1N4749A series of voltage regulator diodes manufactured by Nexperia. The series offers various nominal working voltages ranging from 3.3 V to 24 V, all utilizing the same axial leaded glass package format for consistent mechanical integration across different voltage requirements.

Replacement Considerations

Direct replacements must match the 22 V nominal voltage, DO-41 package, and ±5% tolerance. Verify equivalent power dissipation and thermal resistance values when substituting with components from other manufacturers.
