JANTX1N4614UR-1

Single Zener Diodes Overview

The JANTX1N4614UR-1 is a 0.5 W silicon Zener voltage regulator diode manufactured by Microchip Technology. It features a DO-213AA surface mount package and provides a nominal Zener voltage of 1.8 V with a 5% tolerance. The device operates within a temperature range of -65 °C to +175 °C and includes an internal metallurgical bond for enhanced reliability.

Single Zener Diodes Feature Summary

• Surface mount equivalent to the JEDEC registered 1N4614 series
• Internal metallurgical bond construction identified by the "-1" suffix
• Qualified under JANTX military standards per MIL-PRF-19500/435

Single Zener Diodes Applications

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

Single Zener Diodes Procurement Notes

Verify that the part number strictly matches JANTX1N4614UR-1 to ensure the correct surface mount DO-213AA package and metallurgical bond configuration. Confirm that the JANTX qualification level meets specific project requirements, as commercial equivalents lack this military-grade certification. Ensure compatibility with existing PCB footprints designed for the DO-213AA form factor.

Single Zener Diodes Selection Notes

Select this component when a low-voltage (1.8 V) reference is required in a surface mount format. The JANTX grade offers higher reliability than standard commercial parts but may be less stringent than JANS levels. Consider the 0.5 W power dissipation limit and the specific thermal characteristics of the DO-213AA package during circuit design.

Single Zener Diodes Part Context

This device belongs to the 1N4614 through 1N4627 series of 0.5 W glass Zener diodes. The UR-1 suffix denotes the surface mount DO-213AA variant with an internal metallurgical bond. This series is designed to replace axial-leaded counterparts in compact, high-density electronic assemblies requiring regulated voltage references.
