1N5275BUR-1

Single Zener Diodes Overview

The Microchip Technology 1N5275BUR-1 is a surface mount Zener diode with a nominal voltage of 140 V and a power dissipation rating of 0.5 W. It features a metallurgically bonded glass DO-213AA package, offering a hermetically sealed design suitable for harsh environments. The device operates within a temperature range of -65°C to +175°C and exhibits a maximum reverse leakage current of 0.1 µA at the specified voltage.

Single Zener Diodes Feature Summary

• Hermetically sealed surface mount package with internal metallurgical bond
• Inherently radiation hard per Microsemi specifications
• Non-sensitive to electrostatic discharge (ESD)
• Minimal capacitance characteristics

Single Zener Diodes Applications

• Voltage regulation over broad operating current and temperature ranges
• High-reliability aerospace and defense circuits
• Harsh environment electronics requiring radiation hardness

Single Zener Diodes Procurement Notes

Verify RoHS compliance status as commercial versions are available while military screening options exist. Confirm specific tolerance suffixes if tighter limits than standard 5% are required. Ensure ordering suffixes match exact packaging requirements such as tape and reel configurations.

Single Zener Diodes Selection Notes

Select this component when a hermetically sealed surface mount equivalent to axial-leaded JEDEC types is needed. Consider the 140 V breakdown voltage and 0.5 W power rating for high-voltage regulation tasks. Evaluate thermal resistance values against board layout constraints for optimal heat dissipation.

Single Zener Diodes Part Context

This part belongs to the 1N5221BUR-1 through 1N5281BUR-1 series, providing surface mount equivalents to popular JEDEC registered axial-leaded Zener diodes. The series covers voltages from 2.4 to 200 volts in a compact DO-213AA package, maintaining performance parity with traditional through-hole counterparts.

Single Zener Diodes Replacement Considerations

Direct replacements include other 1N5275 variants with matching voltage and package. Verify that substitute parts maintain hermetic sealing and radiation hardness if these attributes are critical to the application design.
