1N4620UR/TR

Single Zener Diodes Overview

The Microchip Technology 1N4620UR/TR is a glass surface mount Zener voltage regulator with a nominal voltage of 3.3V and a power rating of 0.5W. It operates within a temperature range of -65°C to +175°C and features a standard tolerance of ±5%. The device utilizes a hermetically sealed DO-213AA (SOD80/MLL34) MELF package, offering minimal capacitance and inherent radiation hardness.

Single Zener Diodes Feature Summary

• Hermetically sealed glass DO-213AA MELF package
• Inherently radiation hard design
• ESD nonsensitive per MIL-STD-750 Method 1020

Single Zener Diodes Applications

• Voltage regulation in harsh environments
• Radiation-hardened circuit designs
• Low noise reference applications

Single Zener Diodes Procurement Notes

Verify the specific ordering suffix against official documentation to confirm compliance requirements. Confirm that the TR suffix indicates tape and reel packaging as specified in the datasheet. Ensure the component meets the required environmental and electrical standards for the intended application before procurement.

Single Zener Diodes Selection Notes

Select this component when a robust, radiation-tolerant surface mount Zener diode is required. The 3.3V nominal voltage and 0.5W power rating suit low-power regulation tasks. Consider the DO-213AA package for space-constrained PCB layouts requiring hermetic sealing.

Single Zener Diodes Part Context

This part belongs to the 1N4614UR through 1N4627UR series of 0.5W glass surface mount Zeners. These devices serve as surface mount equivalents to JEDEC registered axial-leaded parts, providing a broad selection of voltages from 1.8V to 100V with standard 5% tolerances.

Single Zener Diodes Replacement Considerations

Direct replacements include other manufacturers' MLL4620 or DO-213AA packaged Zener diodes with matching 3.3V specifications. Verify thermal resistance and impedance characteristics match the original design requirements.
