1N4128UR/TR

Single Zener Diodes Overview

The Microchip Technology 1N4128UR/TR is a glass surface mount Zener voltage regulator with a nominal voltage of 60 V and a maximum power dissipation of 0.5 W. It utilizes a DO-213AA (SOD80/MLL34) MELF package and operates within a temperature range of -65°C to +175°C. The device features a standard ±5% voltage tolerance, a maximum Zener impedance of 400 Ohms at a test current of 250 µA, and a maximum reverse leakage current of 40 µA at 45.6 V.

Single Zener Diodes Feature Summary

• Hermetically sealed glass DO-213AA surface mount package
• Inherently radiation hard design
• ESD nonsensitive per MIL-STD-750 Method 1020
• Minimal capacitance characteristics

Single Zener Diodes Applications

• Voltage regulation in harsh environments
• Radiation-hardened circuit designs
• Surface mount assembly requiring hermetic sealing

Single Zener Diodes Procurement Notes

Verify the specific suffix requirements for your application. The 'TR' suffix indicates tape and reel packaging, while the base part number denotes standard tolerance. Confirm that the manufacturer's datasheet aligns with your thermal and electrical constraints before finalizing procurement orders.

Single Zener Diodes Selection Notes

Select this component when a hermetically sealed surface mount Zener diode is required for high-reliability applications. Ensure the 0.5 W power rating and 60 V breakdown voltage match the circuit design. Consider the DO-213AA footprint compatibility during PCB layout.

Single Zener Diodes Part Context

This part belongs to the 1N4099UR through 1N4135UR series of 0.5 W glass surface mount Zeners. These devices serve as surface mount equivalents to JEDEC registered axial-leaded parts, offering similar electrical performance in a compact MELF-style package suitable for automated assembly processes.

Single Zener Diodes Replacement Considerations

Equivalent axial-leaded parts include the 1N4128 series. Surface mount alternatives within the same family are available with different voltage ratings or tolerance suffixes such as C or D.
