JAN1N3037DUR-1/TR

Single Zener Diodes Overview

The JAN1N3037DUR-1/TR is a surface mount Zener diode manufactured by Microchip Technology, designed for high-reliability applications. It features a hermetically sealed glass MELF package (DO-213AB) and meets MIL-PRF-19500/115 standards. The device provides a nominal Zener voltage of 51 V with a tight tolerance of ±1%. It operates within a temperature range of -55°C to +175°C and dissipates up to 1 W of power.

Single Zener Diodes Feature Summary

• Hermetically sealed double plug glass construction for enhanced reliability
• Metallurgically bonded internal contacts to reduce thermal resistance
• Leadless surface mount design suitable for high-density mounting
• Inherently radiation hard and non-sensitive to electrostatic discharge

Single Zener Diodes Applications

• Voltage regulation over broad operating current and temperature ranges
• High-density electronic circuit assembly
• Military and aerospace systems requiring high reliability

Single Zener Diodes Procurement Notes

Verify the specific military qualification level (JAN, JANTX, or JANTXV) required for your application against the datasheet specifications. Confirm that the DO-213AB MELF package dimensions align with your PCB layout constraints. Ensure compatibility with the specified soldering temperatures and thermal derating curves during system integration.

Single Zener Diodes Selection Notes

Select this component when a precise 51 V reference is needed in a compact surface mount form factor. The ±1% tolerance makes it suitable for precision circuits. Consider the low leakage current and wide operating temperature range (-55°C to +175°C) for harsh environment deployments where standard commercial diodes may fail.

Single Zener Diodes Part Context

This part belongs to the 1N3016B-1 through 1N3045B-1 series, which are surface mount equivalents to JEDEC registered axial leaded diodes. The series offers a Zener voltage range from 6.8 V to 110 V. The JAN1N3037DUR-1 specifically corresponds to the 51 V variant within this lineup, providing a robust alternative to traditional through-hole packages.

Single Zener Diodes Replacement Considerations

Direct replacements include other variants within the 1N3016BUR-1 to 1N3045BUR-1 series from Microchip. Verify that substitute parts match the required voltage tolerance and package outline. Commercial grade versions may lack the hermetic seal and military qualification levels found in the JAN series.
