1N4465DUS/TR

Single Zener Diodes Overview

The JAN1N4465DUS/TR is a surface mount Zener voltage regulator diode manufactured by Microchip Technology. It features a hermetically sealed voidless glass package with an internal metallurgical bond, designed for high-reliability applications where failure cannot be tolerated. The device operates within a junction and storage temperature range of -65°C to +175°C and provides a steady-state power dissipation of 1.5 W at 25°C ambient temperature. Qualified per MIL-PRF-19500/406, it offers robust construction suitable for demanding environments.

Single Zener Diodes Feature Summary

• Hermetically sealed voidless glass package with tungsten slugs
• Internal Category 1 metallurgical bonds for enhanced structural integrity
• Triple-layer passivation for extreme robustness
• Non-sensitive to electrostatic discharge (ESD) per MIL-STD-750 method 1020

Single Zener Diodes Applications

• High-reliability military and aerospace systems
• Voltage regulation in harsh environmental conditions
• Circuit protection requiring radiation hardness
• Critical infrastructure electronics

Single Zener Diodes Procurement Notes

Verify the specific reliability level (JAN, JANTX, JANTXV, or JANS) required for your application, as qualification levels vary. Confirm RoHS compliance status, noting that compliant versions are available only on commercial grades. Ensure ordering suffixes match the desired tolerance and packaging specifications before procurement.

Single Zener Diodes Selection Notes

Select this component when a 1.5 W surface mount Zener diode with high thermal stability and radiation hardness is required. The D suffix indicates a 1% voltage tolerance, offering tighter precision than standard 5% variants. Consider the MELF (D-5A) package dimensions for PCB layout constraints and verify operating current requirements against the electrical characteristics table.

Single Zener Diodes Part Context

This part belongs to the 1N4460US through 1N4496US series of industry-recognized 1.5 W Zener voltage regulators. These devices serve as surface mount equivalents to popular JEDEC registered axial-lead series, providing a compact solution for space-constrained designs without sacrificing power handling capabilities or reliability standards.

Single Zener Diodes Replacement Considerations

Direct parameter-equivalent replacements include other 1N4465 variants from Microchip with different tolerance suffixes (e.g., 1N4465US for 5%, 1N4465CUS for 2%). For non-military grade applications, commercial versions may be considered if radiation hardness and hermetic sealing are not critical requirements.
