1N5274-1/TR

Single Zener Diodes Overview

The Microchip Technology 1N5274-1/TR is a single silicon Zener diode designed for through-hole mounting in DO-35 (DO-204AH) axial leaded packages. It features a nominal Zener voltage of 130 V with a tolerance of ±5% and a maximum power dissipation of 500 mW. The device operates within a temperature range of -65 °C to +200 °C, offering unidirectional characteristics suitable for high-voltage reference applications.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation at 130 V with tight manufacturing tolerances
• Engineered for high-temperature operation up to 200 °C
• Utilizes hermetic glass axial packaging for environmental protection

Single Zener Diodes Applications

• High-voltage precision reference circuits
• Voltage regulation in harsh thermal environments
• Overvoltage protection in sensitive electronic systems

Single Zener Diodes Procurement Notes

Verify compliance status as the component is explicitly noted as non-RoHS and contains lead. Confirm package orientation and lead form upon receipt. Ensure storage conditions maintain the integrity of the glass seal and axial leads. Check datasheet revisions for any updates on electrical limits or testing procedures before final integration into designs requiring strict regulatory adherence.

Single Zener Diodes Selection Notes

Select this component when a precise 130 V reference is required in a standard axial package. The DO-35 form factor supports automated insertion processes. Consider the ±5% tolerance for circuit accuracy requirements. Evaluate the 500 mW power rating against expected thermal loads to ensure safe operating margins under continuous duty cycles.

Single Zener Diodes Part Context

This part belongs to the Microchip Technology single Zener diode family, specifically the 1N5274 series. It shares the 130 V nominal voltage characteristic with variants like the 1N5274BD7 but differs in package type and specific power handling capabilities. The -1 suffix typically denotes the specific axial leaded configuration distinct from surface-mount alternatives.

Single Zener Diodes Replacement Considerations

Direct substitutes include the 1N5274-1 without the tape-and-reel suffix if bulk packaging is acceptable. Verify that alternative sources match the DO-35 package dimensions and 130 V ±5% specification. Cross-reference leakage current and knee impedance parameters to ensure functional equivalence in critical voltage regulation roles.
