1N4614UR-1

Single Zener Diodes Overview

The Microchip Technology 1N4614UR-1 is a surface mount Zener voltage regulator designed for high-reliability applications. It features a DO-213AA package with an internal metallurgical bond, indicated by the -1 suffix. The device provides a nominal Zener voltage of 1.8 V with a standard tolerance of ±5%. It operates within a temperature range of -65°C to +175°C and has a maximum power dissipation of 500 mW.

Single Zener Diodes Feature Summary

• Internal metallurgical bond construction for enhanced mechanical stability
• Surface mount design in DO-213AA package
• Qualified for military standards including JAN, JANTX, and JANTXV levels

Single Zener Diodes Applications

• High-reliability aerospace systems
• Military electronic circuits
• Voltage regulation in harsh environments

Single Zener Diodes Procurement Notes

Verify the specific qualification level (JAN, JANTX, or JANTXV) required for your application, as these variants share the same electrical specifications but differ in manufacturing controls. Confirm RoHS compliance status if environmental regulations apply, noting that some military grades may have specific exemptions. Ensure the DO-213AA footprint matches your PCB design constraints.

Single Zener Diodes Selection Notes

Select this component when a low-voltage reference (1.8 V) is needed in a compact surface mount form factor. The internal metallurgical bond makes it suitable for applications requiring superior resistance to thermal cycling and mechanical shock compared to non-bonded types. Consider the operating temperature range and power dissipation limits relative to your circuit's thermal profile.

Single Zener Diodes Part Context

This part belongs to the 1N4614UR-1 through 1N4627UR-1 series of 0.5 W glass surface mount Zener diodes. These devices are surface mount equivalents of JEDEC registered axial-leaded series. The series offers voltages from 1.8 to 100 V with various tolerance options, catering to diverse voltage regulation needs in commercial and military sectors.

Single Zener Diodes Replacement Considerations

Direct replacements include other 1N4614UR-1 variants with different suffixes indicating tolerance or packaging changes, such as JANTX1N4614UR-1 for higher reliability. Non-bonded equivalents like 1N4614UR without the -1 suffix are electrically similar but lack the internal metallurgical bond.
