1N4734AGE3

Overview

The Microchip Technology 1N4734AGE3 is a silicon Zener diode designed for voltage regulation applications. It features a nominal Zener voltage of 5.6 V with a tolerance of 5%. The device is rated for a power dissipation of 1 W and utilizes a DO-204AL (DO-41) axial through-hole package. This component is RoHS compliant, indicated by the 'e3' suffix, and operates within a temperature range extending up to +175 °C.

Feature Summary

• Provides stable voltage regulation in a standard axial glass encapsulated package
• Offers high thermal stability suitable for demanding operating environments
• Manufactured using silicon technology for reliable unidirectional performance

Applications

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

Procurement Notes

Verify the specific manufacturer source, as this part number may be associated with legacy Microsemi or current Microchip Technology production lines. Confirm that the 'e3' suffix correctly denotes RoHS compliance and lead-free termination requirements for your assembly process. Ensure the DO-41 package dimensions match your PCB footprint constraints before finalizing procurement orders.

Selection Notes

Select this component when a 5.6 V regulation point is required with a 1 W power handling capability. The DO-41 package is appropriate for through-hole mounting techniques. Consider the 5% voltage tolerance and maximum operating temperature limits to ensure compatibility with the target circuit's environmental conditions and precision requirements.

Part Context

This device belongs to the widely recognized 1N47 series of 1-watt Zener diodes. Originally standardized by JEDEC, these components are fundamental elements in discrete semiconductor design. The 1N4734 variant specifically targets the 5.6 V segment of this extensive family, offering a balance between regulation accuracy and power dissipation capabilities.

Replacement Considerations

Compatible substitutes include other manufacturers' 1N4734A parts in the DO-41 package. Verify electrical parameters such as Zener impedance and leakage current against original specifications. Ensure any replacement maintains the same 1 W power rating and axial lead configuration for mechanical interchangeability.
