1N3047BUR-1/TR

Single Zener Diodes Overview

The Microchip Technology 1N3047BUR-1/TR is a surface-mount glass Zener diode in the DO-213AB (MELF) package. It provides a nominal Zener voltage of 130 V at a test current of 1.9 mA, with a maximum impedance of 700 Ohms and reverse leakage current of 0.5 µA. The device dissipates up to 1.5 Watts and operates from -65°C to +175°C. The 'TR' suffix indicates tape-and-reel packaging.

Single Zener Diodes Feature Summary

• Hermetically sealed double-slug glass construction for high reliability
• 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
• Voltage regulation over broad operating currents
• High-reliability applications requiring hermetic sealing

Single Zener Diodes Procurement Notes

Verify the specific electrical parameters against the official datasheet before integration. Confirm that the 'TR' suffix matches the required tape-and-reel quantity and orientation. Ensure the component meets all necessary environmental and screening requirements for the target application.

Single Zener Diodes Selection Notes

Select this component when a 130 V Zener voltage is required in a surface-mount MELF package. Consider the 1.5 W power dissipation capability and the wide operating temperature range. Verify compatibility with the intended PCB footprint and soldering profile.

Single Zener Diodes Part Context

This part belongs to the 1N3016BUR-1 through 1N3051BUR-1 series of surface-mountable Zener diodes. These devices are designed as equivalents to JEDEC registered axial lead parts but utilize the DO-213AB outline for surface mounting. They offer higher power ratings compared to standard small-signal packages.

Single Zener Diodes Replacement Considerations

Equivalent axial lead versions include the 1N3047B. Other series members within the 1N3016BUR-1 to 1N3051BUR-1 family share the same package and features but differ in Zener voltage.
