JAN1N4470DUS/TR

Single Zener Diodes Overview

The JAN1N4470DUS/TR is a surface mount Zener voltage regulator with a nominal voltage of 16 V and a power dissipation rating of 1.5 W. It features a D-5A (SQ-MELF) package and operates within a junction temperature range of -65 °C to +175 °C. The device provides a tight voltage tolerance of ±1% and includes triple-layer passivation for enhanced reliability.

Single Zener Diodes Feature Summary

• Hermetically sealed voidless glass construction using internal metallurgical bonds
• Military qualification per MIL-PRF-19500/406
• Triple-layer passivation for robust protection
• Inherently radiation hard design

Single Zener Diodes Applications

• High-reliability applications where failure cannot be tolerated
• Voltage regulation over broad operating current and temperature ranges
• Radiation-hardened electronic systems

Single Zener Diodes Procurement Notes

Verify the specific suffix 'D' indicates the 1% tolerance level as defined in the part nomenclature. Confirm the 'TR' suffix corresponds to tape and reel packaging requirements. Ensure the component meets the required military qualification levels specified by the application environment.

Single Zener Diodes Selection Notes

Select this component when a 16 V reference requires high precision and ruggedness. The D-5A package suits surface mount layouts needing hermetic sealing. Consider the 1.5 W power rating and thermal resistance characteristics for heat dissipation planning in enclosed environments.

Single Zener Diodes Part Context

This part belongs to the 1N4460US–1N4496US series of 1.5 Watt Glass Zener Diodes. It serves as the surface mount equivalent to the popular JEDEC registered axial-lead series, offering identical electrical performance in a compact MELF form factor suitable for automated assembly.

Single Zener Diodes Replacement Considerations

Equivalent parts include JAN1N4470US (5% tolerance), JANTX1N4470US, and JANTXV1N4470US. Verify that substitute components match the specific 1% tolerance requirement indicated by the 'D' suffix.
