1N3023BUR-1/TR

Overview

The Microchip Technology 1N3023BUR-1/TR is a surface mount Zener diode with a nominal voltage of 13 V and a power dissipation rating of 1 W. It operates within a temperature range of -55 °C to +175 °C. The device features a maximum reverse leakage current of 10 µA, a test current of 19 mA, and a dynamic impedance of 10 Ω at the test point. It utilizes a DO-213AB MELF package.

Feature Summary

• Hermetically sealed glass construction with metallurgically bonded internal contacts 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.

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

Procurement Notes

Verify that the specific part number matches the required military qualification level (JAN, JANTX, or JANTXV) as indicated in the nomenclature. Confirm RoHS compliance status if applicable, noting that lead-free options are available only on commercial grades. Ensure the ordering suffix aligns with the desired tape and reel packaging specifications.

Selection Notes

Select this component when a 1 W surface mount Zener diode with a 13 V breakdown voltage is required. Consider the DO-213AB package dimensions for PCB layout compatibility. Evaluate the thermal resistance characteristics against the expected junction temperature limits to ensure proper heat dissipation under maximum load conditions.

Part Context

This device belongs to the 1N3016BUR-1 through 1N3045BUR-1 series of 1 Watt Surface Mount Zener Diodes. These parts serve as leadless surface mount equivalents to the JEDEC registered 1N3016B-1 through 1N3045B-1 series originally housed in the DO-13 package. They meet the surface mount DO-213AB outline while maintaining hermetic sealing qualities.

Replacement Considerations

Direct parameter-equivalent replacements include the 1N3023B-1 in the DO-41 axial-leaded package. Other series members within the 1N3016BUR-1 to 1N3045BUR-1 family offer different voltage ratings but share identical package and qualification standards.
