JANS1N4469DUS/TR

Single Zener Diodes Overview

The JANS1N4469DUS/TR is a surface-mount Zener voltage regulator manufactured by Microchip Technology. It belongs to the military-qualified 1N4460US–1N4496US series, designed for high-reliability applications where failure is not tolerated. The device features voidless hermetically sealed glass construction with an internal metallurgical bond. It operates within a temperature range of -55°C to +175°C and provides a nominal Zener voltage of 15V with a typical impedance of 9 Ohms.

Single Zener Diodes Feature Summary

• Military qualified per MIL-PRF-19500/406 standards
• Hermetically sealed voidless glass construction
• Internal metallurgical bond for reliability

Single Zener Diodes Applications

• High-reliability aerospace systems
• Military electronic circuits
• Critical voltage regulation in harsh environments

Single Zener Diodes Procurement Notes

Verify the specific suffix DUS against official Microchip documentation to confirm package dimensions and marking details. Confirm that the JANS level meets the required radiation hardness or qualification standards for the target application. Ensure the order specifies the tape-and-reel packaging format indicated by the /TR suffix.

Single Zener Diodes Selection Notes

Select this component when a hermetically sealed, surface-mount Zener diode with military qualification is required. Compare the 15V breakdown voltage and 9 Ohm impedance against circuit requirements. Consider the operating temperature range up to +175°C for thermal management. Verify compatibility with existing PCB footprints for the SQ SMT package.

Single Zener Diodes Part Context

This part is part of the industry-recognized 1.5 Watt Zener diode family from Microchip (formerly Microsemi). It serves as the surface-mount equivalent to through-hole JEDEC registered series, offering a compact solution for space-constrained designs requiring high reliability and hermetic sealing.

Single Zener Diodes Replacement Considerations

Check for direct equivalents within the JAN, JANTX, or JANTXV levels if lower qualification is acceptable. Verify pinout and package dimensions against other surface-mount Zener diodes before substitution.
