1N4469DUS

Single Zener Diodes Overview

The Microchip Technology 1N4469DUS is a military-qualified, surface mount Zener voltage regulator. It features a voidless hermetically sealed glass package with an internal metallurgical bond. The device provides a nominal Zener voltage of 15V at a test current of 17mA. It offers a tight voltage tolerance of ±1%, indicated by the 'D' suffix. The component operates within a junction temperature range of -65°C to +175°C and dissipates up to 1.5W of steady-state power.

Single Zener Diodes Feature Summary

• Hermetically sealed voidless glass construction with tungsten slugs for high reliability
• Qualified per MIL-PRF-19500/406 standards across JAN, JANTX, JANTXV, and JANS levels
• Robust internal metallurgical bonds ensuring resistance to failure in critical applications

Single Zener Diodes Applications

• High-reliability aerospace systems where failure is not tolerated
• Military-grade voltage regulation circuits
• Radiation-hardened electronic designs

Single Zener Diodes Procurement Notes

Verify the specific qualification level (JAN, JANTX, JANTXV, or JANS) required for your application, as availability varies by grade. Confirm RoHS compliance status, noting that compliant versions are typically commercial grade only. Ensure the ordering suffix matches the desired tolerance and packaging format before procurement.

Single Zener Diodes Selection Notes

Select the 1N4469DUS when a precise 15V reference is needed with strict ±1% tolerance. This part is suitable for surface mount layouts requiring hermetic sealing. Consider the 1.5W power dissipation capability and thermal resistance characteristics for heat management in dense circuit boards.

Single Zener Diodes Part Context

This component belongs to the 1N4460US through 1N4496US series of 1.5-watt Zener diodes. These devices serve as surface mount equivalents to popular JEDEC registered axial-lead series. The series covers a broad voltage range from 3.3V to 200V, providing standardized options for various regulation needs.

Single Zener Diodes Replacement Considerations

Equivalent parts include other 1N4469 variants with different tolerance suffixes (e.g., 1N4469US for 5% tolerance). Verify package compatibility and qualification levels when substituting.
