1N3051BUR-1/TR

Single Zener Diodes Overview

The Microchip Technology 1N3051BUR-1/TR is a surface mount glass Zener diode with a nominal voltage of 200 V and a maximum power dissipation of 1.5 W at 25°C. It utilizes a DO-213AB (MELF) package and operates within a temperature range of -65°C to +175°C. The device features a maximum reverse leakage current of 0.5 µA at 152 V, a typical temperature coefficient of 0.100 %/°C, and a maximum Zener impedance of 8000 Ω at the test current of 1.2 mA.

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-reliability applications requiring hermetic sealing
• High-density circuit board mounting
• Voltage regulation over broad operating currents and temperatures
• Radiation-hardened electronic systems

Single Zener Diodes Procurement Notes

Verify that the ordering suffix 'TR' corresponds to tape and reel packaging as specified in the datasheet. Confirm RoHS compliance via the 'e3' designation. Ensure the specific voltage tolerance matches the 'B' suffix requirement of ±5%. Check for available screening prefixes like MQ or MX if military-grade qualification is required.

Single Zener Diodes Selection Notes

Select this component when a 200 V Zener voltage is needed in a surface mount MELF package. The 1.5 W power rating exceeds standard axial equivalents. Consider the low leakage current and radiation hardness for specialized environments. Verify footprint compatibility with the DO-213AB outline dimensions provided in the mechanical data.

Single Zener Diodes Part Context

This part belongs to the 1N3016BUR-1 through 1N3051BUR-1 series, which are surface mount equivalents to the JEDEC registered 1N3016 through 1N3051 axial lead devices. The series offers higher power ratings and improved mounting density compared to traditional through-hole packages while maintaining hermetic glass construction.

Single Zener Diodes Replacement Considerations

Equivalent axial lead parts include 1N3051B. Screening options exist with prefixes such as MQ, MX, MV, or MSP for JAN, JANTX, JANTXV, and JANS standards respectively.
