1N4132UR-1/TR

Single Zener Diodes Overview

The Microchip Technology 1N4132UR-1/TR is a 0.5 W glass surface mount Zener voltage regulator in the DO-213AA package. It provides an 82 V nominal Zener voltage with a standard ±5% tolerance. The device operates within a temperature range of -65°C to +175°C and features a hermetically sealed construction. Electrical characteristics include a maximum reverse current of 0.01 µA, a typical noise density of 40 µV/√Hz, and a maximum Zener impedance of 0.01 Ω.

Single Zener Diodes Feature Summary

• Hermetically sealed glass DO-213AA MELF-style package
• Internal metallurgical bond option available via suffix
• Minimal capacitance for high-frequency stability
• Inherently radiation hard design

Single Zener Diodes Applications

• Voltage regulation in harsh environments
• Reference voltage sources
• Protection circuits requiring radiation hardness

Single Zener Diodes Procurement Notes

Verify the specific ordering suffix against the manufacturer's datasheet to confirm exact electrical tolerances and qualification levels. Ensure the component matches the required JEDEC registration or military specification if applicable. Confirm package dimensions and thermal resistance requirements align with the target PCB footprint before procurement.

Single Zener Diodes Selection Notes

Select this component when a hermetically sealed surface mount Zener diode is required for high-reliability applications. The 1N4132UR-1 variant offers tighter tolerances compared to the standard UR series. Consider the internal metallurgical bond for enhanced mechanical stability in vibration-prone environments.

Single Zener Diodes Part Context

This part belongs to the 1N4099UR through 1N4135UR series of 0.5 W glass surface mount Zener diodes. These devices serve as surface mount equivalents to traditional axial-leaded JEDEC registered parts. The series covers a wide voltage range from 1.8 V to 100 V, providing flexibility for various reference and regulation needs.

Single Zener Diodes Replacement Considerations

JEDEC registered 1N4132 axial equivalents are available. Surface mount variants with different tolerance suffixes (C or D) may be considered if tighter voltage accuracy is required.
