Single Zener Diodes Procurement Notes

Verify current availability status as this specific part number may be subject to discontinuation or end-of-life restrictions. Confirm that the required RoHS compliance and environmental specifications align with project constraints. Ensure the procurement channel provides authentic Microsemi products to guarantee performance reliability and traceability.

Single Zener Diodes Selection Notes

Select this component when a 4.7 V regulation point is required with strict tolerance limits. The 1 W power rating suits moderate current applications, while the axial package facilitates easy integration into through-hole PCB designs. Consider the extended temperature range suitability for demanding operational environments.

Single Zener Diodes Part Context

This device belongs to the 1N4732 series of 1-watt Zener diodes produced by Microsemi. The 'e3' suffix indicates lead-free composition compliant with environmental directives, while '/TR13' denotes the specific reel packaging configuration used for automated assembly processes.

Single Zener Diodes Replacement Considerations

Direct substitutes include the 1N4732A and 1N4732AU variants. Verify that alternative sources maintain identical voltage tolerances and thermal characteristics to ensure circuit compatibility without redesign.
