JAN1N3026DUR-1/TR

Single Zener Diodes Overview

The JAN1N3026DUR-1/TR is a surface mount Zener diode manufactured by Microchip Technology, designed for high-reliability applications. It features a nominal Zener voltage of 18 V with a test current of 14 mA and a maximum dynamic impedance of 25 Ohms at the specified test point. The device operates within a junction temperature range of -55°C to +175°C and dissipates up to 1.0 W of power. It utilizes a DO-213AB (MELF) glass package and holds military qualification per MIL-PRF-19500/115.

Single Zener Diodes Feature Summary

• Hermetically sealed double plug glass construction with metallurgically bonded internal contacts for enhanced reliability.
• Qualified under MIL-PRF-19500/115 standards for JAN, JANTX, and JANTXV military levels.
• Leadless surface mount MELF package suitable for high-density circuit layouts.
• 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 assemblies requiring low parasitic characteristics
• High-reliability systems utilizing hermetic sealing

Single Zener Diodes Procurement Notes

Verify that the specific ordering suffix matches the required tolerance level and RoHS compliance status. Confirm the military qualification grade aligns with project specifications. Ensure the tape and reel packaging configuration meets automated assembly requirements. Validate that the component lot traceability satisfies quality assurance protocols.

Single Zener Diodes Selection Notes

Select this component when a leadless surface mount Zener diode with strict military reliability standards is required. The DO-213AB package offers a compact footprint compared to axial equivalents. Consider the thermal resistance and derating curves for high-temperature environments. Verify that the 18 V breakdown voltage fits the target circuit design constraints.

Single Zener Diodes Part Context

This part belongs to the 1N3016B-1 through 1N3045B-1 series, which are surface mount equivalents of JEDEC registered devices. The series provides a wide selection of Zener voltages from 6.8 V to 110 V in the same glass MELF package format.

Single Zener Diodes Replacement Considerations

Equivalent parts include JAN1N3026DUR-1 and JANTX1N3026DUR-1. These variants share the same electrical characteristics but differ in reliability qualification levels.
