1N4732AE3/TR13

Overview

The 1N4732AE3/TR13 is a silicon Zener diode manufactured by Microsemi Corporation, designed for voltage regulation applications. It features a nominal Zener voltage of 4.7 V with a tight tolerance of ±5%. The device is rated for a maximum power dissipation of 1 W and operates within an extended temperature range from -65°C to +150°C. Packaged in the DO-204AL (DO-41) axial through-hole format, it delivers a maximum Zener impedance of 8 Ohms. The component is supplied in reel packaging and complies with RoHS standards.

Feature Summary

• Provides stable voltage regulation with a nominal 4.7 V output and ±5% tolerance.
• Engineered for high thermal stability across a wide operating temperature range.
• Constructed in a robust plastic encapsulated DO-204AL axial package.

Applications

• Voltage reference circuits requiring precise potential levels
• Overvoltage protection stages in electronic systems
• General-purpose voltage regulation tasks

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.

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.

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.

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.
