Procurement Notes
Verify authenticity by purchasing directly from Micro Commercial Components or authorized distributors to avoid counterfeit parts. Confirm that the product meets specific quality standards for handling and storage. Ensure the component is not utilized in life support devices without express written approval from the manufacturer.
Selection Notes
Select this component for applications requiring hermetic sealing and high thermal stability up to 200°C. The DO-41G package supports through-hole mounting. Verify that the 1.0W power rating and 5% voltage tolerance align with circuit requirements. Consider derating current by 20% when used with capacitive loads.
Part Context
This part belongs to the 1N4728A through 1N4761A series manufactured by Micro Commercial Components. The series covers Zener voltages ranging from 3.3V to 75V. All units share identical mechanical characteristics and utilize the DO-41 glass case design.
Replacement Considerations
Cross-reference with other manufacturers offering 1N4737A specifications in the DO-41 package. Ensure equivalent electrical parameters such as 1.0W power dissipation and 5% voltage tolerance are met before substitution.
FAQ
What is the maximum operating temperature?
The maximum operating temperature is +200°C.
