JAN1N3029DUR-1

Single Zener Diodes Overview

The JAN1N3029DUR-1 is a surface mount Zener diode manufactured by Microchip Technology, designed for high-reliability applications. It features a hermetically sealed glass MELF (DO-213AB) package and meets MIL-PRF-19500/115 standards. The device provides a nominal Zener voltage of 24 V with a tight tolerance of ±1%. It operates within a junction 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

Single Zener Diodes Applications

• Voltage regulation over broad operating current and temperature ranges
• High-density electronic assemblies requiring low parasitic characteristics
• High-reliability military and aerospace systems

Single Zener Diodes Procurement Notes

Verify the specific suffix 'D' indicates the 1% voltage tolerance variant when sourcing. Confirm that the component adheres to the MIL-PRF-19500/115 qualification requirements for your intended environment. Ensure compatibility with the DO-213AB footprint during PCB layout. Check for RoHS compliance status if required by your assembly specifications.

Single Zener Diodes Selection Notes

Select this component when a precise 24 V reference is needed in a compact surface mount form factor. The 1% tolerance makes it suitable for precision circuits where standard commercial tolerances are insufficient. Consider the DO-213AB package dimensions against available board space. Evaluate the thermal derating curve if operation near the maximum power dissipation limit is anticipated.

Single Zener Diodes Part Context

This part belongs to the 1N3016B-1 through 1N3045B-1 series, which serves as the surface mount equivalent to the traditional JEDEC registered axial leaded devices. The series covers a wide Zener voltage range from 6.8 V to 110 V. The JAN prefix denotes a specific level of reliability qualification under military standards.

Single Zener Diodes Replacement Considerations

Direct replacements include other variants within the 1N3016BUR-1 to 1N3045BUR-1 series that share the same DO-213AB package. Verify that any substitute matches the 24 V nominal voltage and the required ±1% tolerance specification.
