1N3024BUR-1/TR

Overview

The Microchip Technology 1N3024BUR-1/TR is a surface mount Zener diode with a nominal voltage of 15 V and a maximum power dissipation of 1 W. It utilizes a DO-213AB (MELF) package and operates within a temperature range of -55 °C to +175 °C. The device features a test current of 17 mA, a maximum reverse leakage current of 10 µA at 11.4 V, and a dynamic impedance of 0.25 Ohms. It offers a voltage tolerance of ±5% and a temperature coefficient of 0.088 %/°C.

Feature Summary

• Hermetically sealed glass MELF construction for high reliability
• Metallurgically bonded internal contacts for enhanced durability
• Leadless surface mount design suitable for high-density applications
• Inherently radiation hard

Applications

• Voltage regulation over broad operating currents and temperatures
• High-reliability military and aerospace circuits
• High-density electronic assemblies requiring low parasitics

Procurement Notes

Verify the specific ordering suffix against the manufacturer's nomenclature guide to confirm RoHS compliance status and exact qualification level. Ensure the tape and reel specifications align with automated assembly requirements. Cross-reference the part number with the official datasheet to validate electrical parameters before procurement.

Selection Notes

Select this component for designs requiring a robust surface mount Zener diode with hermetic sealing. Consider the 1 W power rating and wide operating temperature range for demanding environments. Evaluate the low leakage current and stable impedance characteristics for precision voltage reference applications where thermal stability is critical.

Part Context

This device belongs to the 1N3016B-1 through 1N3045B-1 series, which are leadless surface mount equivalents to JEDEC registered axial diodes. Qualified per MIL-PRF-19500/115, the series provides JAN, JANTX, and JANTXV military grades alongside commercial options, ensuring compatibility with legacy axial designs while offering modern surface mount advantages.

Replacement Considerations

Direct replacements include other 1N3024 variants in the same series such as 1N3024B-1 or 1N3024BUR-1 without the tape and reel suffix, provided the package outline and electrical ratings match the design requirements.
