1N3039BUR-1/TR

Single Zener Diodes Overview

The Microchip Technology 1N3039BUR-1/TR is a surface mount Zener diode in the DO-213AB (MELF) package. It provides a nominal Zener voltage of 62 V at a test current of 4.0 mA. The device features a maximum Zener impedance of 125 Ohms and a maximum reverse leakage current of 10 µA. It supports a maximum regulator current of 15 mA and operates within a junction temperature range of -55 °C to +175 °C. The component has a DC power dissipation rating of 1.0 W and exhibits a voltage temperature coefficient of 0.104 %/°C.

Single Zener Diodes Feature Summary

• Hermetically sealed glass MELF construction with metallurgically bonded terminals for high reliability.
• Leadless surface mount design suitable for high-density applications with low parasitic requirements.
• Inherently radiation hard and non-sensitive to electrostatic discharge.

Single Zener Diodes Applications

• Voltage regulation over broad operating current and temperature ranges.
• High-reliability military and aerospace electronic systems.
• High-density circuit board layouts requiring surface mount components.

Single Zener Diodes Procurement Notes

Verify that the specific ordering suffix matches the required tolerance level, as the 'B' designation indicates a 5% voltage tolerance. Confirm RoHS compliance status if environmental regulations apply, noting that RoHS versions are typically available only on commercial grades. Ensure the tape and reel specifications align with automated assembly equipment requirements before finalizing procurement orders.

Single Zener Diodes Selection Notes

Select this component when a 62 V reference is required in a leadless surface mount package. Consider the 1.0 W power dissipation limit and derating curves for thermal management. Verify that the 5% voltage tolerance meets circuit precision requirements. Evaluate the DO-213AB package dimensions against available PCB real estate and mounting surface expansion coefficients.

Single Zener Diodes Part Context

This part belongs to the 1N3016B through 1N3045B series of 1 Watt surface mount Zener diodes. These devices serve as leadless equivalents to JEDEC registered axial-leaded parts but utilize the DO-213AB outline. The series offers various voltage options from 6.8 V to 110 V with different tolerance levels including JAN, JANTX, and JANTXV qualifications.

Single Zener Diodes Replacement Considerations

Direct replacements include other 1N3039 variants such as 1N3039B-1 or 1N3039BUR-1D depending on tolerance needs. Cross-reference with equivalent MELF packages from other manufacturers ensuring identical voltage, power, and hermetic sealing specifications.
