JAN1N4469CUS

Single Zener Diodes Overview

The JAN1N4469CUS is a surface mount Zener voltage regulator with a nominal breakdown voltage of 15.0 V and a test current of 17.0 mA. It features a maximum dynamic impedance of 25 Ohms at the test point and a maximum reverse leakage current of 0.05 µA at 12.0 V. The device operates within a junction temperature range of -65 °C to +175 °C, dissipating up to 1.5 W at 25 °C ambient temperature. It utilizes a D-5A MELF package with a hermetically sealed voidless glass construction.

Single Zener Diodes Feature Summary

• Hermetically sealed voidless glass package with internal metallurgical bonds for robust construction
• Qualified per MIL-PRF-19500/406 for high-reliability applications
• Inherently radiation hard design
• Non-sensitive to electrostatic discharge

Single Zener Diodes Applications

• Voltage regulation in military-grade electronic systems
• High-reliability circuits where failure cannot be tolerated
• Radiation-hardened environments

Single Zener Diodes Procurement Notes

Verify that the specific ordering suffix matches the required tolerance level and RoHS compliance status. Confirm the reliability qualification level (JAN) aligns with project specifications. Ensure the package type corresponds to the intended surface mount footprint. Check for any specific environmental or testing requirements mandated by the governing procurement standards.

Single Zener Diodes Selection Notes

Select this component when a 15.0 V reference is required in a surface mount configuration. The 2% tolerance designation indicates tighter voltage accuracy compared to standard commercial versions. Consider the 1.5 W power dissipation capability and wide operating temperature range for thermal management planning. Verify compatibility with existing PCB layouts designed for the D-5A MELF form factor.

Single Zener Diodes Part Context

This part belongs to the 1N4460US through 1N4496US series of 1.5 Watt glass Zener diodes. These devices are industry-recognized equivalents to popular JEDEC registered axial-lead series but packaged for surface mount assembly. The series offers extensive voltage selections from 3.3 to 200 volts with various tolerance options available.

Single Zener Diodes Replacement Considerations

Direct replacements include other JANS1N4469US variants if higher reliability levels are needed. Commercial grade 1N4469US parts may substitute if military qualification is not required. Axial lead 1N4469 equivalents can be used if board space allows for through-hole mounting.
