JAN1N4482US/TR

Single Zener Diodes Overview

The JAN1N4482US/TR is a surface mount Zener voltage regulator with a nominal breakdown voltage of 51V and a maximum dynamic impedance of 60 Ohms at the test current. It operates within a junction temperature range of -65°C to +175°C and dissipates up to 1.5W of steady-state power. The device utilizes a void-less hermetically sealed glass package with an internal metallurgical bond, conforming to MIL-PRF-19500/406 standards for high-reliability applications.

Single Zener Diodes Feature Summary

• Hermetically sealed void-less glass construction with internal metallurgical bonds
• Military qualification per MIL-PRF-19500/406
• Triple-layer passivation for robustness

Single Zener Diodes Applications

• High-reliability voltage regulation
• Circuits requiring radiation hardness
• Applications intolerant to component failure

Single Zener Diodes Procurement Notes

Verify that the specific ordering suffix matches the required reliability level and tolerance. Confirm RoHS compliance status if applicable, as it may be restricted to commercial grades. Ensure the tape and reel packaging aligns with manufacturing requirements. Validate datasheet revisions against procurement specifications.

Single Zener Diodes Selection Notes

Select this component when military-grade reliability and radiation hardness are mandatory. The D-5A MELF package suits space-constrained surface mount designs. Verify thermal derating curves for operating temperatures exceeding 25°C. Consider the 5% standard tolerance unless tighter specifications are explicitly required by the design.

Single Zener Diodes Part Context

This part belongs to the 1N4460US through 1N4496US series of 1.5-watt glass Zener diodes. These devices share identical mechanical and electrical characteristics, differing primarily in their nominal Zener voltage ratings. The series provides a broad selection from 3.3V to 200V for various regulation needs.

Single Zener Diodes Replacement Considerations

Direct replacements include other parts within the 1N4460US–1N4496US series or equivalent MIL-PRF-19500/406 qualified components. Verify package dimensions and pinout compatibility before substitution.
