1N4617UR-1/TR

Single Zener Diodes Overview

The Microchip Technology 1N4617UR-1/TR is a surface mount Zener diode in the DO-213AA (MELF) package. It provides a nominal Zener voltage of 2.4V at a test current of 250 µA. The device features a maximum Zener impedance of 1.0 Ohm and a maximum reverse leakage current of 1.0 µA. Rated for 500 mW power dissipation, it operates within a junction temperature range of -65°C to +175°C. The 'TR' suffix indicates tape and reel packaging.

Single Zener Diodes Feature Summary

• Hermetically sealed glass DO-213AA MELF package with internal metallurgical bond
• Qualified per MIL-PRF-19500/435 for JAN, JANTX, JANTXV, and JANS reliability levels
• Non-sensitive to electrostatic discharge per MIL-STD-750 method 1020
• Inherently radiation hard

Single Zener Diodes Applications

• Voltage regulation over broad ranges of current and temperature
• High reliability applications requiring military qualification
• Radiation-hardened circuit designs

Single Zener Diodes Procurement Notes

Verify the specific reliability level required (JAN, JANTX, JANTXV, or JANS) as prefixes modify screening but not electrical function. Confirm RoHS compliance status, as commercial versions may differ from military qualified parts. Ensure the TR suffix matches the intended tape and reel handling requirements for assembly.

Single Zener Diodes Selection Notes

Select this component for surface mount designs requiring hermetic sealing and high reliability. The 2.4V rating suits low-voltage reference applications. Consider the negative temperature coefficient of -0.075%/°C for thermal stability analysis. Verify that the 500 mW power dissipation meets the circuit's thermal budget under derating conditions.

Single Zener Diodes Part Context

This part belongs to the 1N4614 through 1N4627 series of 500 mW metallurgically bonded glass surface mount Zener diodes. These devices serve as surface mount equivalents to JEDEC registered axial-leaded 1N4614 through 1N4627 series components. The series offers voltages from 1.8 to 100V with various tolerance options.

Single Zener Diodes Replacement Considerations

Commercial equivalents include CDLL4617-1. Axial-leaded replacements are available as 1N4617-1 in the DO-35 package.
