1N5273BDO35

Single Zener Diodes Overview

The Microsemi Corporation 1N5273BDO35 is a 0.5 W glass axial-lead Zener diode in the DO-35 (DO-204AH) package. It provides a nominal Zener voltage of 120 V with a standard tolerance of ±5%. The device operates within a temperature range of -65°C to +175°C and features a maximum reverse current of 100 μA at 86 V. Its maximum Zener impedance is 900 Ω, and it exhibits a voltage temperature coefficient of +0.110 %/°C.

Single Zener Diodes Feature Summary

• Hermetically sealed glass axial-lead construction for reliable operation
• Capable of regulating voltage across a broad operating current and temperature range
• Inherently radiation hard per MicroNote 050
• Minimal capacitance characteristics suitable for high-frequency applications

Single Zener Diodes Applications

• Voltage regulation circuits requiring stable reference voltages
• Overvoltage protection in electronic systems
• Clamping applications in signal processing paths

Single Zener Diodes Procurement Notes

Verify that the component matches the specific JEDEC registered type number and suffix requirements for your design. Confirm RoHS compliance status if required by your manufacturing process, as non-compliant variants exist within the series. Ensure the supplier provides documentation confirming the hermetic seal integrity and adherence to MIL-PRF-19500 screening levels if military-grade reliability is mandated.

Single Zener Diodes Selection Notes

Select this component when a precise 120 V reference is needed with tight ±5% tolerance. Consider the thermal resistance and power derating curves for high-temperature environments. Evaluate the dynamic impedance specifications against the noise sensitivity of the target circuit. Verify lead length requirements during mounting to ensure accurate electrical parameter measurement.

Single Zener Diodes Part Context

This part belongs to the popular 1N5221 through 1N5281B series of 0.5 watt Zener Voltage Regulators. The series offers a wide selection from 2.4 to 200 volts. The 'B' suffix specifically denotes a standard voltage tolerance of plus or minus 5%, distinguishing it from other tolerance options available in the family.

Single Zener Diodes Replacement Considerations

Equivalent parts include 1N5273A for 10% tolerance or 1N5273C/D for tighter tolerances. Surface mount equivalents are available in the MLL5221 to MLL5281B series using the DO-213AA MELF package.
