1N4621UR/TR

Single Zener Diodes Overview

The Microchip Technology 1N4621UR/TR is a 500 mW Zener voltage regulator in the surface mount glass DO-213AA package. It provides a nominal Zener voltage of 3.6 V with a standard tolerance of ±5%. The device features an internal metallurgical bond and operates within a junction temperature range of -65°C to +175°C. Qualified per MIL-PRF-19500/435, it offers high reliability for demanding applications.

Single Zener Diodes Feature Summary

Internal metallurgical bond construction for enhanced reliability
Hermetically sealed glass DO-213AA surface mount package
Qualified to JAN, JANTX, JANTXV, and JANS levels per MIL-PRF-19500/435

Single Zener Diodes Applications

Voltage regulation over broad current and temperature ranges
High reliability electronic systems requiring radiation hardness
Surface mount circuits needing hermetic sealing

Single Zener Diodes Procurement Notes

Verify the specific qualification level (JAN, JANTX, JANTXV, or JANS) required for your application, as the base part number may be prefixed accordingly. Confirm RoHS compliance status if applicable, noting that commercial versions are available in RoHS compliant configurations while military grades follow different standards. Ensure the TR suffix indicates tape and reel packaging consistent with EIA-481-1-A specifications.

Single Zener Diodes Selection Notes

Select this component when a 3.6 V reference is needed in a surface mount form factor. Consider the low noise density characteristics for sensitive analog circuits. Evaluate the thermal derating requirements based on the specified junction-to-ambient resistance. Verify that the DO-213AA footprint matches the design constraints.

Single Zener Diodes Part Context

This device belongs to the 1N4614UR-1 through 1N4627UR-1 series of 500 mW metallurgically bonded glass surface mount Zener diodes. These components serve as surface mount equivalents to JEDEC registered axial-leaded series, offering similar electrical performance in a compact MELF-style package suitable for automated assembly processes.
