1N4132UR/TR

Single Zener Diodes Overview

The Microchip Technology 1N4132UR/TR is a 0.5-watt glass surface mount Zener voltage regulator with an 82V nominal breakdown voltage. It utilizes a hermetically sealed DO-213AA (MELF) package and operates within a temperature range of -65°C to +175°C. The device features a standard 5% voltage tolerance, a maximum reverse current of 0.01 µA at the rated voltage, and a typical temperature coefficient of 0.095%/°C.

Single Zener Diodes Feature Summary

• Hermetically sealed glass MELF package for environmental protection
• Capable of regulating voltage across a broad operating current and temperature range
• Inherently radiation hard construction suitable for demanding environments

Single Zener Diodes Applications

• Voltage regulation in surface mount circuit designs
• Reference voltage generation in electronic systems
• Overvoltage protection circuits

Single Zener Diodes Procurement Notes

Verify that the specific part number includes the TR suffix to confirm tape and reel packaging configuration. Ensure the required voltage tolerance aligns with the standard 5% specification provided for this base model. Confirm compliance requirements match the RoHS compliant e3 designation if applicable to your manufacturing process.

Single Zener Diodes Selection Notes

Select this component when a compact surface mount Zener diode is required for high-temperature applications up to 175°C. The 0.5W power rating and 82V breakdown voltage define the operational limits. Consider the tight thermal resistance specifications and derating curves when designing the PCB footprint to ensure reliable heat dissipation under steady-state conditions.

Single Zener Diodes Part Context

This component belongs to the 1N4099UR through 1N4135UR series of 0.5-watt glass surface mount Zeners. These devices serve as surface mount equivalents to traditional axial-leaded JEDEC registered parts. The series offers extensive voltage selection from 1.8V to 100V in various tolerance grades.

Single Zener Diodes Replacement Considerations

Direct replacements include other manufacturers' DO-213AA packaged Zener diodes with matching 82V ratings and 0.5W power dissipation capabilities. Verify that any substitute maintains the same hermetic sealing and radiation hardness characteristics if those are critical design constraints.
