1N4614UR

Single Zener Diodes Overview

The Microchip Technology 1N4614UR is a Zener voltage regulator featuring a nominal voltage of 1.8 V with a tolerance of ±5%. It operates within a power dissipation range of 500 mW and utilizes a surface mount DO-213AA glass package. The device supports an operating temperature range from -65°C to 175°C, ensuring reliability in demanding environments.

Single Zener Diodes Feature Summary

• Constructs with internal metallurgical bond for enhanced structural integrity
• Hermetically sealed glass encapsulation provides environmental protection
• Qualified per MIL-PRF-19500/435 standards for high-reliability applications

Single Zener Diodes Applications

• High-reliability military systems requiring JANS level qualification
• Spacecraft electronics subject to extreme thermal variations
• Avionics circuits demanding stable voltage regulation under harsh conditions

Single Zener Diodes Procurement Notes

Verify the specific suffix (e.g., UR-1) against official datasheets to confirm metallurgical bonding and MIL-PRF-19500/435 compliance. Ensure procurement channels are authorized to guarantee authenticity and traceability for qualified components. Confirm RoHS status and packaging details prior to ordering.

Single Zener Diodes Selection Notes

Select this component when a low-voltage reference of 1.8 V is required in a surface-mount form factor. The DO-213AA package suits automated assembly processes. Consider the ±5% tolerance and 500 mW power rating for circuit design margins. Verify thermal management capabilities for operation up to 175°C.

Single Zener Diodes Part Context

This part belongs to the 1N4614UR through 1N4627UR series of 500 mW Zener diodes. These devices offer voltages ranging from 1.8 V to 100 V in various tolerances. The series is designed for surface-mount applications using glass DO-213AA packages with internal metallurgical bonds.

Single Zener Diodes Replacement Considerations

Equivalent parts include CDLL4614E3 and JANTX1N4614UR-1. Verify that substitutes match the 1.8 V Zener voltage, 500 mW power rating, and DO-213AA package dimensions. Confirm if MIL-PRF-19500/435 qualification is required for the application.
