1N3022BUR-1/TR

Overview

The Microchip Technology 1N3022BUR-1/TR is a surface mount glass Zener diode designed for high-reliability applications. It features a hermetically sealed DO-213AB package with a nominal Zener voltage of 12 V at a test current of 21 mA. The device supports a maximum power dissipation of 1.5 W and operates within a temperature range of -65°C to +175°C. Electrical characteristics include a maximum reverse leakage current of 1.0 µA, a typical voltage temperature coefficient of 0.065 %/°C, and a maximum Zener impedance of 9 Ω.

Feature Summary

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

Applications

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

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm packaging configuration. The TR suffix indicates tape and reel packaging per EIA-481-1-A standards. Confirm RoHS compliance status by checking for the e3 suffix in the part number. Ensure the selected variant matches the required screening level if military specifications are necessary.

Selection Notes

Select this component when a surface mount solution is required for Zener regulation with high power handling capabilities. The DO-213AB outline provides a direct footprint alternative to axial lead equivalents while maintaining hermetic sealing. Consider the 1.5 W power rating and wide operating temperature range for demanding environments where standard SMD packages may be insufficient.

Part Context

This device belongs to the 1N3016BUR-1 through 1N3051BUR-1 series of surface mountable glass Zener diodes manufactured by Microsemi (now Microchip). The series offers a wide voltage selection from 6.8 to 200 volts. These components serve as surface mount equivalents to JEDEC registered axial lead devices but feature improved power ratings and hermetic sealing properties.

Replacement Considerations

Equivalent axial lead parts include the 1N3022B series. Surface mount alternatives within the same family include the MLL3022B designation. Screening options such as JAN or JANTXV are available via MQ, MX, or MV prefixes.
