1N3047B-1/TR

Single Zener Diodes Overview

The Microchip Technology 1N3047B-1/TR is a surface mount glass Zener diode with a nominal voltage of 130 V and a power dissipation rating of 1.5 W at 25 °C. It features a DO-213AB outline, hermetically sealed double-slug glass construction, and metallurgically enhanced contacts. The device operates within a temperature range of -65 °C to +175 °C, has a maximum reverse leakage current of 0.5 μA, and a typical voltage temperature coefficient of 0.095 %/°C.

Single Zener Diodes Feature Summary

• Hermetically sealed double-slug glass construction for high-reliability applications
• Metallurgically enhanced internal contact design for lower thermal resistance
• Leadless surface mount package suitable for high-density mounting
• Inherently radiation hard

Single Zener Diodes Applications

• High-density circuit board mounting
• High-reliability electronic systems
• Voltage regulation over broad operating currents and temperatures

Single Zener Diodes Procurement Notes

Verify the specific ordering suffix against official documentation to confirm screening levels and RoHS compliance status. Confirm that the TR suffix indicates tape and reel packaging per EIA-481-1-A standards. Ensure the component meets the required MIL-PRF-19500/115 specifications if military-grade screening is necessary for the application.

Single Zener Diodes Selection Notes

Select this component when a 1.5 W surface mount Zener diode is required in a leadless package. Consider the 130 V nominal voltage and 0.095 %/°C temperature coefficient for precision regulation needs. Evaluate the thermal resistance characteristics and ensure the footprint matches the recommended DO-213AB layout for optimal heat dissipation.

Single Zener Diodes Part Context

This part belongs to the 1N3016BUR-1 through 1N3051BUR-1 series of surface mountable Zener diodes. It serves as the surface mount equivalent to the JEDEC registered 1N3016 through 1N3051 axial lead devices but offers a higher power rating of 1.5 Watts compared to the traditional through-hole versions.

Single Zener Diodes Replacement Considerations

Equivalent axial lead parts include the 1N3047B. Surface mount equivalents are MLL3047B or MLL3047B,e3.
