1N4754AE3/TR13

Overview

The Microchip Technology 1N4754AE3/TR13 is a single axial-lead Zener diode housed in a DO-41 (DO-204AL) package. It features a nominal Zener voltage of 39 V with a tolerance of ±5% and a maximum power dissipation of 1 W. Key electrical parameters include a Zener impedance of 60 Ohms, a maximum reverse leakage current of 5 µA at 29.7 V, and a test current of 6.5 mA. The device operates within a temperature range of -65°C to +150°C and is supplied in a reel packaging format.

Feature Summary

• Provides stable voltage regulation at a nominal 39 V level for circuit protection and reference applications.
• Constructed with silicon technology to ensure reliable unidirectional operation under specified thermal conditions.
• Designed for through-hole mounting using the standard DO-41 axial leaded package configuration.

Applications

• Voltage regulation in low-power electronic circuits
• Overvoltage protection for sensitive components
• Reference voltage generation in analog signal processing

Procurement Notes

Verify the specific suffix designation against official Microchip documentation to confirm exact tolerance and packaging specifications. Ensure compatibility with existing board layouts regarding the DO-41 footprint and axial lead dimensions. Confirm RoHS compliance status as required by project regulations before finalizing procurement orders.

Selection Notes

Select this component when a precise 39 V Zener reference is required with moderate power handling capabilities. The ±5% tolerance offers tighter regulation than standard variants, suitable for precision applications. Consider the 1 W power rating and operating temperature range to ensure adequate thermal management within the target system environment.

Part Context

This part belongs to the 1N47xx series of Zener diodes manufactured by Microchip Technology. It is an evolution of legacy designs, incorporating modern manufacturing processes while maintaining pin-out compatibility with traditional DO-41 packages. The 'E3' suffix typically indicates lead-free composition compliant with environmental directives.

Replacement Considerations

Cross-reference with 1N4754A-T3 for similar electrical characteristics. Verify that substitute parts match the 39 V Zener voltage, 1 W power rating, and DO-41 package dimensions to ensure mechanical and functional interchangeability without circuit redesign.
